Testimonials + Before and After


I just wanted to express my special note of appreciation to Jacy for upgrading my new Sig MCX 556 Rattler with Romeo and Juliette red dot optics and other accessories. I am very pleased with this Rattler purchase at the Centennial Gun Club and Jacy was also very helpful in my making these important purchase decisions. I plan on making further upgrades and purchases in the near future, and will be looking forward to Jacy’s expertise in this regard.

Bart, As I expected, you did an outstanding job with the Colt 9mm Combat Commander I dropped off. I had no idea why it would be having cycling issues. Since you completed the work we’ve shot over 250 rounds with it. It’s now accurate AND reliable. Thanks for helping me with hard to fix guns over the years. I always know where to bring them.

I came into the Centennial Gun Club to see what they had for used handguns. This lead me to find a robust selection of used handguns and my purchasing one. I was torn between a standard Springfield XDS 9mm and a Mod 2 XDS 9mm with a Sig RomeoZero micro reflex sight. I decided on the standard XDS and took it home.

After a couple hours I started deciding that I wanted the Mod 2 with the reflex sight and decided I would return the next day and inquire about exchanging. Unsure what the staff would say, I entered and spoke to the Director of Gunsmithing and Used Guns, Bart Miller. He didn’t even think twice. He looked over the returning pistol and said okay, lets do it. WOW. I did not expect it to go that smooth.

He said they pride themselves in customer service and satisfaction and then proved it to me. On top of that, he even found a magazine in the back so I could walk out the door with two mags! Again, above and beyond! Thank you very much Bart. I will absolutely be back for more guns, ammo, range time and of course a membership with your store.

Thanks again for your help. I look forward to seeing you again and possibly working with you.


I brought this year old pistol into you all as it was double feeding and had worked flawlessly until it didn’t! I was concerned, as it was an expensive pistol and a long wait to get it. So, I was kinda bummed that it was having problems. Jacy put me at ease with his helpful and friendly manner and assured me that he could fix it and would have it to me one day later.

Sure enough, I got a call the next day and it was ready. I paid my $35, yes $35 and Jacy told me he modified the extractor/ejector and tidied it up. I test fired it and it worked flawlessly. My race gun was back on line!

I just wanted to take a minute to thank Jacy for his kindness, friendly manner and extreme competence. I am very impressed with your skill, service and professionalism. That goes for everyone I came in contact with at Legacy.

Today, Bart took my disassembled Ruger 22/45 and reassembled it while showing me how to put the hammer in the fired position in order to allow reassembly. He was patient, thorough in his explanation and very friendly.

Really wanted to give you all an attaboy and tell you how much I appreciate you and that Centennial has this service on site, it’s one of the reasons I belong. Thanks for your helpful, friendly and terrific service.


What outstanding customer service the Centennial Gun Club provided me this week. I own an automatic that I carried when a police officer, but having changed careers haven’t fired in several decades. My wife used it for some firearms training and experienced consistent jamming. I brought it into your gunsmith shop – my first time visiting the facility. Steve provided a very welcoming/friendly greeting and asked how he could help. He listened very patiently. I was expecting to need to leave the weapon to be looked at over a period of time. Steve demonstrated a strong understanding of firearms and after looking it over asked if he could fire it to see what might be the problem. In a short time, he came back and advised the problem was not the firearm – but was the magazine. In a matter of minutes the problem was diagnosed and recommendations provided. WOW.

I was amazed and very grateful. As icing on the cake – Steve even thanked me for letting him shoot my sidearm!

What a great representative and knowledgeable staff you have. Two other gentlemen – whom I did not get their names – also weighed in and one did a modification of the magazine lips.

Thank you for having such a great team. I will certainly be sharing my experiences with your team to my friends.

I cannot express how thankful I am for the work Bart did on repairing my dad old Winchester Model 70, 30-06. My dad had passed away in late 2020 after a hard-fought battle with cancer. His old Winchester was what my dad had taught me how to shoot with and had left it to me to pass down to my son. I cannot count the number of memories I have hunting with my dad, with his rifle by his side. His rifle was the one I used to harvest my first deer and my first elk.

A week after he passed away, a relative picked up his rifle and had taken it elk hunting. I had reservations about this, and I had offered the use of any of my personal rifles, including of the exact same model but they refused, saying that he had been looking forward to that hunt and had offered the use of his rifle as he knew it would most likely be his last hunting season.

When the rifle was finally returned, it was broken in half. It had been dropped and snapped at the wrist of the stock. I understand accidents happen, but the grief was almost unbearable as I was still mourning his death. I had taken the rifle to several gun smiths around town, and all of them had told me that the rifle was beyond repair, and I was better off turning it into wither a “wall hanger” or buying a new stock for it, but I couldn’t bring myself to go with either of those options.

Many of the memories I have hunting and shooting my dad and his rifle were etched in the character of that stock. From the wear on the finish from years carrying it in a scabbard while riding our horses through the mountains and hills we hunted to the scratches left behind on the wood while moving through heavy brush. He was excited that I would teach my son to hunt and shoot with that rifle as well as share with my son similar memories he had shared with me.

When I had taken the rifle to Bart and his team, they noted to me the severity of the damage and that there could be a risk of the rifle breaking again due to the recoil. Although Bart had made this clear, he was confident in their abilities to repair and conserve the rifle. On what would have been my dad’s 72nd birthday, six months after he passed away, I got a call from Bart asking me to come in and look at the work he had done to my dad’s rifle. I hurried to his shop and upon examining the rifle, I could not tell that it had ever been broken. The detail of the work Bart had done left the rifle looking as it was prior to it being broken. He completely conserved the rifle and thus all the memories I had shared with my dad. Even going as far as to fix the checkering that had been smashed during the impact of the fall that had caused the break. Every grain of wood is in place and all the character of the stock there. I cannot see with my naked eye any remnant of the break.

Bart’s work is solid and the rifle is completely functional, leaving me with zero worries about the pressure of the recoil causing the break to reappear. I cannot thank him and his team enough for the attention to detail and quality of work. The quality of craftsmanship is beyond anything I had ever expected.

Although my dad’s Winchester is priceless to me and I would have paid any amount to get it back to what is was prior to it being broken, the cost of the work was less than what I would have paid for a brand new stock. The care and attention to detail Bart had taken working on my dad’s rifle allows for the legacy of my dad and his rifle to live on and for me to share a lifetime of memories with my son.


Mike, thanks for the excellent job you did in replacing and adjusting my sights on my Glock 43.  You’ve also been great at answering my questions about my Glock and also the upcoming attachment of a suppressor to my hunting rifle and AR.  Your skill, professionalism, and friendly spirit are very much appreciated. I’ll be back!

In regards to the shotgun fitting you did.

Got the 20ga Beretta out to Kiowa Creek this morning. It fit great and was 77 out of the 100. Always struggled to exceed 50% before with that gun and between your tips and the 5/8 increased LOP, the improvement was immediate. I just got back from three days of pheasant hunting in SD and was very successful. Will probably bring in my 12ga at some point this winter.


So far my experience with Centennial Gun Club has been superb!! Looking forward to shedding off some rust and improving skills. I want to keep advancing thru your courses.

Dean S.

I had some gunsmith work done here by Bart Miller. My issue was a nasty chip in my rifle stock that was somewhat large and in a very bad location that significantly reduced the value and eye appeal of my rifle. Bart was able to expertly repair the chip and did a masterful job of blending the new wood with the 50 year old finish. I was impressed by the craftsmanship and the price. It’s very hard to find skilled gunsmith labor for a reasonable price in the metro area but I found my new goto guy for all my future gunsmithing needs.

Jason R.

Your man Jacy got my M17 rear sight fixed in no time! I cannot say enough about what a warm and expert guy he is. So glad to have this level of expertise available to us as members of CGC!

To Centennial Gun Club:

Just a note and a word of thanks to Mr. Bart Miller (Gunsmith). I would like to thank Mr. Miller for working so diligently on my match CZ pistols using his expertise and “magic.” He was very patience with me to get the pistols right for me. For the record, he did not replace with any aftermarket parts, just used the stock parts. I am guessing he just adjusts and polishes the parts to make the pistols just that much better.

My last match I won by seventeen hundreds of a second. I think his hard work for me paid off.

Once again, thank you so much.

R. S.
I own a Glock 23 that I purchased and installed a laser light to.   I had tried to attempted to align the light myself with negative results. I contacted two people to assist me in this challenge and both advised me to just remove the laser because they are worthless.  My contact with these people made me feel like a super novice who knew nothing about firearms. FYI , I retired as a criminal investigator after more the. 20 years. Now to the reason I  am writing this. I contacted Mike Mitchell at Centennial Gun Club and told him my challenge.   Mike listened and advised me that it was probably an easy fix and I should bring it in so he could look at it.  He gave me an abbreviated idea of what might wrong that I could easily understand. When I brought my Glock in and Mike looked at it, he advised to come back in 15 minutes. When I returned he showed me how it now worked. Mike’s customer service skills are over and above what is normal in the business world and you should be commended for his hiring. Thank you and Mike for correcting my challenge with my weapon.
Paul N.

I wanted to tell you about my recent experience with selling two revolvers to you at the Centennial Gun Club. I had seen you “advertising” at the club and from emails that I had received. I had two revolvers that I did not use and did not want to keep so I brought them over to the club and spoke to Lucas. He explained to me in detail how the process worked and that he would need about 30 minutes to review the revolvers and obtain a price.

When I came back he had a price much higher than I had expected…which came as a very pleasant surprise. I agreed to the price and the transaction was very simple, quick and seamless. Your team handled all of the needed paperwork which was even better.

Thank you for a great experience. Should I have other firearms that I wish to sell I will not hesitate to use your service or recommend you to others who may be in the same situation.

Thanks again.


I took my Browning Citori in to Legacy for some work. The weapon was a present from my Dad when I graduated from college, so has a bit of sentimental value over and above the fact that it shoots really well. Turns out that over the last almost 40 years I wore out some bits on the action. Picked up my Citori this afternoon, and Bart not only took care of that issue, but tightened up other parts of the action/fit as well. It feels as tight and smooth as the day I got it.

Hat’s off to Bart and his staff!
I now know where all of my weapons go if they need work.

Jim W.

Have been a customer of Legacy Gunsmithing for a few years and trust them completely with my firearms. Among other things, Bart and his team restored a cherished Browning Hi Power to magnificence.

More recently, I asked Bart to fit a barrel to my Rizzini/Sigarms Aurora shotgun. The gun is several years old and the replacement barrel was different enough to require significant fitting.

Bart did an amazing job. It locks up tight as a bank vault and ejects shells in a parallel arc. His work and attention to detail are both second to none. Fitting shotgun barrels seems to be a declining commodity, but Bart knows his craft.

I completely recommend Bart Miller and Legacy Gunsmithing for all types of repairs and projects, but particularly for those heirloom guns you want to be perfect.

David J. Thrower

They don’t look down on or act condescending to women and new shooters. They want you to be safe and accurate. The training is great and they don’t make you feel stupid for asking questions. They are the only place I care to go. You’ll be happy that you went there too!


“What is really outstanding is the level of service provided; this shop is the only place I will entrust my guns to going forward. Bart and his staff are experts at their trade and true customer service experts as well. My hat is off to Bart and his shop!”

Paul DiMarchi

I’m writing to offer some feedback on a .308 to 6.5 Creedmoor conversion and accurizing Mike had completed for me in March. Unfortunately due to other obligations I was unable to do any load development until the beginning of August. Now that I’ve had the opportunity to explore the capabilities of the new rifle I find it difficult to not to share with you how I feel about Mike’s work.
Yesterday I took the rifle out for its intended purpose, a Bicycle 5 x 5 (2.5” x 3.5” Target / 5 String / 500 yards). The card reflects two 5 strings shot independently 20 mins apart in varied wind conditions approximated from 10 to 20 mph. You can see 7 of 10 hit with 2 groups of 3 and once on target the rifle printed approximately 1” groups both times at 500 yards. This level of precision is proving to be consistent.
Mike’s build is easily the most consistent rifle I’ve owned or shot. There’s a good deal of work that goes into that level of precision beyond the build, however the gunsmith is who makes that level possible to begin with. From an OEM Remington 700 .308 Mike produced what I confidently consider a .25 MOA rifle, but it’s not just the workmanship worth noting. It’s important to point out Mike’s attentiveness, professionalism, and counsel was appreciated and a vital part of the process.
My thanks to Mike, and Legacy. I look forward to the next one.

Every time I have interacted with your shop, I’m impressed by the people that work there. Today I received such exceptional service, that I wanted to send a note saying thank you and recognizing Kyle McIntosh.

I purchased a new gun on Saturday and it had an odd problem where it would not fire the last round of each magazine. I really wanted to avoid sending it to Smith and Wesson as my experience is their turn around times are quite long.

I brought the gun to your shop and Kyle began asking me about it before I even got to the counter. He then took the gun to the range, test fired it and did some adjustments. Nothing seemed to work, so he asked if I could leave the gun with him for additional troubleshooting.

He continued to troubleshoot, figured it out, completed the fix, and got back to me all within a few hours. This was a new gun and he understood my frustration, and really went out of his way to help. 

Kyle was great to work with and ensured that I will be a life long customer of Legacy Gunsmithing.
Ethan W.

I wanted to pass along my special thanks to Mike, Jeff, and others at Legacy Gunsmithing for their great service and support.  I bought a used Ruger rifle that had a poorly installed muzzle brake.  They diagnosed the problem quickly and helped me come up with the best plan of action to get it fixed. Then they quickly got it fixed.

I also had some minor issues with a couple other rifles that they fixed right on the spot for no charge…amazing service and I will certainly be back!   They are friendly and eager to help, which is a real plus in today’s world.   Truly, they are the best of the best, and I was very lucky to have found them.

Having served in the US Air Force for nearly 37 years, I understand the importance of great support and service, so I am proud to give them my absolute highest recommendation  to support any gunsmithing needs you may have!

Thanks again!


I have used four Gunsmith’s over the past 40+ years, in three different locations in the U.S. Bart Miller is the best Gunsmith I have ever relied upon. Specifically, the quality of work, quick turn around time, superb skills and customer service, and reasonable costs, allow me to say Legacy Gun Smith is the best. We are fortunate to have Bart and his team at Centennial Gun Club. Most recently, I took a completely locked up pistol with a round in the chamber to Bart for advise, because I was certain I needed to return this new pistol to the manufacturer. Bart calmly took the pistol, and in about 10 minutes, presented me with a defective bullet, and thus a perfectly functioning pistol…free of charge. I have used Bart and his team for multiple upgrades and am totally satisfied with their level of perfection.



HISTORYThis is an old (1981) LT 20 gauge 1100 whose receiver had been terribly scratched, worn, and abused…..Bart first skillfully removed all signs of scratches and abuse, but attempts to restore the factory blue failed twice…..the receiver had been overheated during the assembly of the mag tube (silver solder) when first manufactured… it would not take a uniform blue that looked good…..and since Bart refused to give this customer something that he was not proud of, Bart went the extra mile and had the receiver sealed with CeraKote (Premium Elite midnight blue) and the results are beautiful! From a timing and satisfaction perspective, Bart bent over backwards to make sure I was happy with the work and the turnaround time.


This may seem like an unusual compliment but I’d like to thank Centennial Gun Club for helping me decide NOT to buy a particular handgun. I’ve never seen another gun store that will let you try a pistol or rifle before deciding whether to buy it. (Used firearms, not new, I understand.) There was a used pistol that looked like it might fit the bill for what I was looking for but after firing it I decided it wasn’t a great fit for me. Club staff actually encouraged me NOT to buy the gun when seeing that I wasn’t loving it. I really appreciate that level of looking out for your customer. It’s part of the reason I’ve encouraged many friends to buy their guns at Centennial Gun Club and why I purchase from you as well.


I wanted to let you and your staff know how much I appreciated the fine excellent and professional service and expertise all of you showed me when I gave you four of my 1911 handguns to check over, clean and work on one with a trigger issue. I shot all of them and they performed great, no issues at all.

I appreciated the fast turn a round on my carry Gun as well. I shot it in the IDPA match this week and it was a pleasure to have no malfunctions and totally enjoyed it once again.

Thanks for being at the club and there for us.

The Signature Used Gun Difference

A Legacy Gunsmiths signature on each certification form is our way of assuring you we have personally inspected this firearm and it has passed our certification process.

Here’s a behind the scenes look at Legacy Gunsmithings used gun purchasing and certification process

The Initial Inspection

We take the time to get familiar with each gun that comes in for sale or trade by first giving it a thorough visual inspection. We check for things like:

  • Cracked stocks
  • Bulged barrels
  • Surface rust
  • Has it been altered

Then we look at the make, model, caliber, accessories etc. We also try to gain some insight as to its history from the owner. We’ll explain the specifics of how our purchasing program is structured so the customer can be a part of the process as it moves along.

Establish Finish Originality

Perhaps no other factor contributes more to, or detracts from, a gun’s value than whether it’s been refinished or not. A gun can easily lose half its book value, or more, if it doesn’t have the original finish. In addition, the difference between a properly refinished gun and a poorly done one can also make a huge difference. It’s important to keep in mind that gun value blue books only give values for guns in their original condition.

Note: (Making a determination on originality is not always an easy task. This is where the experience of our gunsmith staff comes into play. For over 30 years we’ve had the privilege of handling a wide variety of guns in their original pristine condition.

The first hand experience we’ve gained from having personally performed restorations over the last 3 decades helps give us valuable insight verifying originality since we had the opportunity to see the gun before and after it was redone.)

Percentage of Condition

Condition, like beauty, is in the eye of the beholder and therefore open to interpretation. Fortunately, the gun Blue Books recognize this and have done a great job of providing the “tools” to help establish percentage of condition both by description and photos.

Establish Fair Market Value

We typically start the research by looking at industry standard firearm Blue Books. If we need to find more information, or additional comparable guns for sale, we’ll often go to the internet. Since the internet has countless listings being added and removed on a daily basis it can also be a great barometer for the gun markets ever fluctuating pricing.

Finding Common Ground

1) We review the information we’ve gathered with the customer to make sure they’re comfortable with everything.

2) Our goal is to reach common ground on the gun’s value. 

3) If everyone’s comfortable and confident with the information and the terms we then move forward. 

4) After the gun is purchased, it goes through our certification process.

The Certification Process

The top 2 priorities we keep in mind when we certify a gun is to make sure it is:

  1. Safe to shoot
  2. Reliable

We perform numerous checks on a gun to make sure it is within safe operating specifications.

We inspect each gun thoroughly, lock, stock and barrel.

The list of items we check can be quite involved and depends on the type of gun, of course. There are times when it makes sense to certify the gun before we buy it.

Sometimes we run into situations where, although the gun works, it’s out of spec. When this happens, we’ll take the time to bring it back to the proper spec’s. Think of it this way, just because your car runs, doesn’t mean it’s running correctly or at peak performance. In other words, things can “run” and still be out of spec!

If everything passes inspection we test fire the gun before it ever goes out for sale to the public. We provide a certification form with each used gun we sell with our gunsmith’s signature on it to show it has passed our certification process and it’s safe, reliable and ready to go. (There are of course a few exceptions like when there’s no ammo available or it’s an unfired gun).

Bart Miller

Bart Miller has made a living as a Gunsmith in the Denver area for over 30 years. He graduated the local Gunsmith School, the Colorado School of Trades, in 1984 and sits on their advisory board. He is also a certified Gunsmithing instructor. Bart started his gunsmith career in 1984 when he was 21 working for Gart Bros. He managed the repair shop for most of the 15 years he worked there. He and a business partner started a small retail gun store that was open for 5 years and specialized in gunsmithing which he managed. Bart sold his interest in the business and set up a gunsmith shop at a local gun store when an opportunity to work for Bass Pro Shops became available. He was employed by Bass Pro Shops for 10 years where he managed a 5 man gunsmith shop as well as their Fine Gun Room. While at Bass Pro he created an annual shooting event called the Generations Classic Sporting Clays Shoot where folks of all ages could get together to pass along our shooting heritage, introduce them to shotgun shooting sports and get the chance to experience what it’s like to shoot collector and high end classic shotguns from around the world. Bart has gained a strong following performing shotgun fittings for all ages. He works closely with several local professional shooting instructors. He has been a guest multiple times on local ESPN radio stations covering various aspects of gunsmithing and gun collecting. Bart has spoken at Brownells Gunsmith Career Fair several times presenting two seminars he created called, “Trouble Shooting Firearms” and “How to Provide a Great Customer Service Experience.” These seminars are now part of the curriculum at the Gunsmith school. Bart wrote an article called “If this old gun could talk” for an online magazine.   It gives a behind the scenes look at the firearm trade-in process and the importance a gunsmith shop can play. It also taps into the historical and sentimental aspects of gun ownership. Bart has performed countless appraisals for the companies he has worked for over 3 decades and his own mobile appraisal business. Bart has re-barreled guns for a local S.W.A.T. team and does design and custom work for people with special shooting needs. One of his hobbies is to do R&D work and build prototypes. He has been issued two patents. His primary gunsmithing focus is on the design and function of guns, what makes them run and the importance of customer service.
