Testimonials + Before and After


It has been such a pleasure dealing with you!  When Warren Watson of Warren Watson School of Shotgunning recommended that I use you for my shotgun fitting ( because you are one of the best gun fitters he has used over the years) I didn’t doubt his word!  So I took my new Browning White Lightning to you at Centennial Gun Club.  You spent time with me, explaining exactly what you you would do to my gun.  You were also able to simulate how the new fit would feel, by using temporary materials on the stock so I could mount it.  You gave me a reasonable completion date as well.

I have had many compliments on your work since that first meeting.  I was so please, that I returned a month later with my Browning XT!  You had kept files on my first gun, so you were able to duplicate the stock work on my 12 gauge.

Many, many thanks for your expertise and service.  I am certain that Centennial Gun Club feels fortunate to have you there with them.



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.


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.

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!


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.


This review is strictly regarding the team at legacy gunsmith inside the gun club. I recently came into possession of about 7 different guns. I first took them to somewhere else to try to sell them and was treated like some idiot. I can only assume because I didn’t look like a typical gun guy they wouldn’t give me the time of day or any fair offers. (joke’s on you as I’m a military veteran with more gun experience than they seemed to have) what a refreshing change of pace coming into see the team here. They were all super friendly and let us drop off the guns and go about our day. When we came back, they gave us the market price on all our guns, even the ones they couldn’t buy. For the ones they could purchase, they made a fair price (70% of market value) and cut us a check! Even gave us an offer for a gun they they didn’t originally want but did it because we sold them the ones they did! Best of all, the customer service here represents a true American way. We love our country, our guns, and our family… They treat their customers like family. For that reason, we will only do business here moving forward.

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.


Just a quick note to say how pleased I am with Master Gunsmith Bart Miller’s work on my Auto Ordnance m1 carbine.

What was wrong with it? Nothing. Except it looked brand new, right out of the box, which it was. I am a WWII reenactor and I wanted a rifle that looks like it’s “been there”. That’s where Bart came in. I’m not sure how he did it, but now it looks exactly like an original paratrooper carbine that I own. Outstanding! Now I will be using that carbine for parades, living history and static displays.

It’s one thing to be adept at repairing a firearm, which is smack dab in the middle of Bart’s wheelhouse. But it’s quite another thing to have the ability, talent and desire make a gun look authentic, like in my case.

What Bart has the ability to do is artistic, (he probably could make a handsome living in Hollywood), and Centennial Gun Club is extremely fortunate to have Mr. Miller on staff.

To borrow a line from The Terminator, “I’ll be back.”

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.

Roberto D.

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.

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.

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.


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.

Dave J.
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.
“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!!!”

My employees needed a break from work today. It has been one of those weeks. So i told them we would go shooting. I saw that you had a gunsmith shop onsite and since i had never been to the CGC it helped the decision of where to go. The shooting was great. We have Nothing but positive comments to make.

However my experience with the gunsmiths was impressive. The first gunsmith saw me lingering and came out to ask if he could help with anything He knew exactly the rifle I was talking about without even seeing it. He knew the history and design of the scope mount He told me to bring it on in and they would look. He brought jacy out and I explained the issue with the 1903 my father put together and sporterized when i was quite young. This is the first year my youngest son will have the chance to hunt big game with me so I want him to use this gun that was made to create a strong family bond and a legacy of love for the outdoors. Jacy took it back and went over it quickly and when he came back out with it he had some good info and tips. My gunsmith TJ retired so I have been hesitant about handing over a rifle that is so important to me but your crew seems so professional and knowledgeable that I will have no hesitation.

“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

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 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.

I would like to extend a thank you to your staff at Centennial Gun Club. On Friday January 11, my friends and I went to get some afternoon shooting in, and I brought along my wife’s AR that I had been struggling with. I had been trying for quite some time to remove the barrel nut in order to swap to a different forestock, but had been unable to get it loose.

Your team was outstanding in the friendly attitudes and was able to get the barrel nut removed for me. I greatly appreciated their willingness to help! This sort of customer service seems to be rare in our world today, so it is refreshing to see such generosity and enthusiasm for their craft. I must say this sort of act does not go unnoticed and has made a customer for life!

Please extend my gratitude to your wonderful staff.

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.


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!


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!

Ray S.

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 am writing to thank you for allowing Jacy to help me today.  I brought in our school track starter pistol because it was having trouble. Jacy worked on the starter pistol, although it was not his expertise, and brought it back to working condition.  He saved our school nearly $300 if we were to purchase a new one.  We struggle with not having enough funds all of the time.  You guys are the best.  I will always give you my/our business.  Thank you once again and we will hopefully see you soon.

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.
