Bart Miller has spent more than four decades taking things apart to understand how they work. Today, as SDI’s gunsmithing instructor, he passes that knowledge on to the next generation of gunsmiths. He brings decades of precision machining, custom builds, and shop-floor experience directly into the curriculum. Most recently, he built out SDI’s Manual Lathe course as its subject matter expert.
From the Upper Midwest to a Career at the Bench
Bart’s story starts the way a lot of gunsmiths’ stories do. He grew up in the upper Midwest, learned to shoot, and spent time outdoors. He also took mechanical things apart just to see how they worked. “Someday I plan on putting them back together,” he jokes. It’s a nod to the curiosity that eventually became a profession.
That curiosity took shape in 1984. Bart graduated from a gunsmithing school in Colorado and started his career as a professional gunsmith that same year. Since then, he has managed gunsmith shops and used-gun programs. He’s led teams of up to six gunsmiths and co-founded a retail gun store built around gunsmithing services.
The work has spanned the full range of the trade. Bart has handled general repairs, hand-fitted fine double guns, and completed full restorations. He’s tackled precision machining and one-of-a-kind custom projects. He’s also helped several retail firearms businesses build or expand their own gunsmithing operations, giving him a perspective that goes beyond the bench and into how a gunsmithing operation actually runs.
A Career Built on Craftsmanship and Customer Service
Ask Bart, SDI’s gunsmithing instructor, what’s guided him through more than 40 years in the trade, and the answer isn’t a specific project or tool. It’s a philosophy. Quality craftsmanship, attention to detail, and treating people right have guided his whole career. He’s distilled these principles into what he calls The Gunsmith’s Creed.
That commitment to service extended beyond his own shop. Brownells invited Bart to speak at its Career Fair for five consecutive years. There, he shared practical troubleshooting techniques with the next wave of gunsmiths. He also emphasized a lesson he’s carried his whole career: technical skill only goes so far without genuine customer service behind it.
The Project That Meant the Most
Of all the builds and repairs in Bart’s career, one stands out as the most rewarding.
A customer came to Bart wanting to take up target shooting as a hobby. Physical limitations made handling a firearm conventionally impossible for him. His left arm was fused straight. His right arm was fused at a 90-degree angle, with movement only in his trigger finger. Most people would have called it out of reach. Bart and his customer decided otherwise.
Together, they designed a solution: a modified two-wheel cart converted into a mobile shooting station. It safely transports the rifle and magazines to the range. It also holds the rifle in a horizontal “parked” position, so the shooter can maneuver into place. A mounted laser handles the sighting, since shouldering the firearm wasn’t an option. The result gave the customer independent control of his firearm and the ability to pursue the sport on his own terms.
“Seeing his determination and achieving his goal was priceless,” Bart says. “He’s also a really good shot.”
It’s the kind of problem-solving that doesn’t show up in a textbook: the ability to look at a barrier and engineer a way around it. It’s also exactly the mindset Bart now works to instill in SDI students.
Bringing a Holland & Holland Back From the Dead
Not every memorable job at the bench starts with a happy customer story. Some start with a phone call about a shattered stock and a client hoping it isn’t as bad as it sounds.
One of the toughest repairs of Bart’s career involved a Holland & Holland .375 H&H. It’s a serious collector’s rifle chambered in a heavy-recoiling round. The stock had snapped clean in half during shipping. Repairing a broken stock is never simple. Getting the two halves positioned correctly and reinforced so they’ll hold under recoil is a job that punishes shortcuts. This one carried extra weight, too. The rifle wasn’t headed for a display case. It was headed to Africa, where it would see real use on dangerous-game hunts, absorbing the heavy recoil of the .375 H&H round hunt after hunt.
Bart rebuilt the stock to hold up under exactly that kind of use. He stayed in touch with the customer afterward. He even got the chance to inspect the rifle himself after three hunts in Africa. It showed no cracking and no signs of failure, every indication it was ready to go back out for three more. For a collector-grade double rifle built to be used hard in the field, that’s the only verdict that matters.
Building a Shooting Heritage Event From the Ground Up
Bart’s contributions to the shooting community haven’t been limited to the workbench. One of the events he’s most proud of creating is the Generations Classic Sporting Clays Shoot. Bart developed it for Bass Pro Shops and hosted it at a local gun range.
The idea behind Generations Classic was simple but deliberate. It brought different generations together to shoot on teams, in a participation-based, non-competitive format designed to pass shooting heritage from one generation to the next. Grandparents, parents, and kids shared a clays course instead of competing against each other. The event also let participants handle and shoot classic and collector firearms from around the world. It offered hands-on training for first-time shooters of every age, too.
It’s the same instinct that runs through everything else in Bart’s career: take the trade seriously, and make sure it gets handed down.
Teaching the Next Generation as SDI’s Gunsmithing Instructor
These days, Bart’s focus has shifted from the bench to the classroom, where he now works full-time as a gunsmithing instructor. The two aren’t as different as they might seem. As SDI’s Firearms Specialist, Bart helps shape the curriculum across firearms technology courses. He reviews, outlines, and recommends content. He also serves as the subject matter expert for select courses, writing content and recording instructional videos himself. His most recent contribution was building out the Manual Lathe course. He translated decades of precision machining experience into a structured learning path for students who’ve never stood at a lathe before.
For Bart, teaching isn’t a departure from gunsmithing. It’s a continuation of it. The same principles that guided his shop work guide his teaching now: craftsmanship, problem-solving, and doing right by the people you serve. He’s passing those same principles on to SDI students preparing to enter the trade.
“I remain passionate about sharing the practical skills, craftsmanship, and problem-solving techniques I’ve developed throughout my career,” Bart says, “and helping prepare the next generation of gunsmiths to carry on the traditions of quality, craftsmanship, and professionalism that define our trade.”
