Testimonials + Before and After


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.

I want to thank you for the outstanding, and I mean outstanding, job you did for me finishing the stock work on my custom model 98 Mauser, as well as in repairing the 60-year old double set trigger mechanism on my Wilbur Hauck single shot rifle.  Because there are only 148 known Hauck single shot rifles in existence, there are precious few who even know his name.  When my rifle began developing trigger issues, I brought it to you because of your reputation in dealing with high quality weapons and performing top-notch work.  Clearly you exceeded my expectations.
In my book you definitely deserve the title of master gunsmith as you are many grades above and beyond the majority of guys who hang out a shingle claiming to know their way around sophisticated gunsmithing but in reality know very little.

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 picked up a new pistol at a gun show that had a horrible trigger, and I was incredibly disappointed. But Bart, the gunsmith at the Centennial Gun Club, did an amazing “trigger job” on it and it now feels as clean and crisp (if not better) than the trigger on my Kimber. Thanks Bart!!!”

I brought my LCP in last night intending to drop it off and wait for 3-4 weeks.  I was greeted by Jeff, who said “hold on while I go take a look at it”.  He took it to the back, and came back within 10 minutes with my LCP performing as it should.  All he asked for was “good will”.  Amazing.  Your team will certainly be at the top of my list of providers when I need any future gunsmithing services… and I’ll tell anybody else I come across, too.  Thanks to Jeff, you, and your entire team for being customer service oriented, and for being a great bunch of guys.

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.

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 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!”

I had recently purchased a used gun from Centennial Gun club and it took out on the range last week. I was having trouble getting it to fire even when it went into battery. There was a usual issue with the firing pin and trigger assembly that needed some minor changes. I took it into the gunsmith. The team was very polite and professional. They took their time with me on the range that day trying to diagnose the problem. After just several days of trying it out on the range with the gunsmiths, they were able to fix the issue. The gun now works flawlessly! (I would like the thank gun smiths Kyle and Bart and anyone else who helped me) I would highly recommend this smith to anyone. The smiths there are extremely knowledgeable and friendly.

The best part is since I bought the gun there at their location everything was covered 100% under their guaranteed warranty.


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!

I wanted to thank you again for the fine work you did on my .375 H&H Magnum rifle. As the target below shows, this is a terrifically accurate and functional rifle. It will be with me in December when I hope to fill my Elk tag, using the same factory Federal Premium with 260 grain AccuBonds with which I sighted the rifle in. The group was shot from the bench at 100 yards.

This rifle began as a factory stock Remington 700 XCR II. I chose to replace the factory stock with a Bell & Carlson Medalist Sporter stock in Weatherby configuration, glass bed the barreled action into the bedding block, replace the X-Pro trigger with a Timney 510 trigger set to 3.5 lbs, and add optics. You did these modifications and suggested that I mount my scope with Leupold QR quick release bases and rings that you installed. I could not be more delighted with your work, advice, turnaround time and price. This is my go-to Elk rifle and will accompany me to Alaska when I go to fish and hunt. This is the third and latest rifle you’ve assembled and tuned for me and each shoots as well as this one…it will not be the last.

Thanks again for your craftsmanship, advice and help. It continues to be a pleasure to work with you.


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!

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.

This is a customer from your great Centennial Gun Club I have recently found interest in firearms last year but unfortunately in my family I am the 1st to explore the nature of guns and firearm laws in general and as you can imagine this can be very uneasy to talk to salesman and experts in the field since I am a minority and I have found to be treated differently although I’m proud to be a American and look at everyone to be human first which unfortunately isn’t the case by visiting different gun ranges and stores I’m writing this email just to say thank you to your staff and gun smiths for making me feel like a person first and foremost long story short I will continue to shop and use your gun range versus others for that simple fact alone I may not be rich since I’m your average hard working American but I appreciate the small things in life that matter most to me in short.

I have asked Bart and his team to replace the factory sights on a Springfield Armory XD(m) and two XD40 SCs with Trijicon HD sights. As defense pistols, I had wanted night sights with a wider rear notch and high visibility front post with an orange dot. The team completed the job swiftly and, in my range test today, the sights were spot on for windage and elevation. Now Bart has done a variety of superb gunsmithing jobs for me over the last several years; I am completely satisfied with his latest work.

I have taken a number of different firearms into to Bart and have received excellent advice, recommendations, and always superb workmanship by him and his team. He has replaced sights, glass-bedded three rifle actions for me, inspected service rifles and kept me successfully shooting across a range of disciplines for more than five years. Legacy Gunsmithing is my “Go-To” first stop for any firearms questions and I trust them completely. A hearty thanks and well-done for this recent job…it will certainly not be the last!


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.

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.


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.



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.


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.

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.

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.

If you are looking for a gunsmith that you can trust look no further. I have a Savage 30.06 that I have had to other gunsmiths and never got nothing but B.S. and a bill, Until I was told to bring it to Legacy.

They helped me solve a long time misfiring issue that turned out to be a savage Firing spring. These men at Legacy helped me resolve this issue professionally and timely due to my upcoming hunt. They took responsibility for the issue after looking at the gun once and stood by their commitment to service till my gun was fixed and I can assure you it was not an easy fix as it took several times of trying on their part till they figured out the issue and called Savage and got me the replacement parts. Then let me test fire it there to make sure we finally fixed my long time issue.

And wouldn’t you know it less than a week later I was on my on my hunt and had a bull Elk walk out in front of me @ 243 yards and It was a one shot one kill scenario, My First Bull Elk EVER! Thank you Legacy and Thank you Bart for helping me have a reliable and dependable gun for what turned out to be my most unforgettable hunting experience yet. You are a master of your craft and I will never let anyone touch my firearms but you and your Staff.

Your grateful customer,


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!


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!


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 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.

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 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.
