Welcome to JR Precision LLC

I grew up chasing whitetails and pulling bass out of lakes and rivers in rural southern Wisconsin, and somewhere along the way I got hooked on rifles—especially the kind that can reach out and touch something a long way off. The more I shot, the clearer it became: a rifle that’s just “accurate enough” is fine, but one that’s been built with real care and top-shelf components feels completely different behind the trigger. That realization sent me down the rabbit hole of chasing precision, constantly tuning, tweaking, and upgrading until everything clicked.

These days I’ve turned that obsession into JR Precision, where I help other shooters get their rifles dialed in exactly the way they want—whether it’s a no-nonsense hunting rig or a full-on competition build.

My home shop sits just outside Lone Rock, nestled in the heart of the Driftless Area. It’s a small, quiet place where things move at a relaxed pace. Every rifle I touch gets my full attention; every customer gets a one-on-one conversation. Need a barrel swap, a crisp trigger, or a ground-up custom build? I’ll take whatever time it takes to make sure it leaves here shooting lights-out. No rush, no upsell—just straight talk and solid work.

I’ve always believed that real precision demands focus, and that means specializing in what I know best: bolt-action rifles built from the ground up for accuracy, whether they’re headed to the deer woods or the firing line at a match. As the owner of JR Precision, I take it seriously—giving honest advice from the first call through the final range session, treating your rifle like it’s my own, and never letting it go out the door until I’d be proud to shoot it myself.

I make it a point to actually listen to what you want and how you shoot. This isn’t about throwing parts at a problem; it’s about ending up with a rifle that feels right in your hands and performs exactly the way you pictured it. From start to finish, I want the whole process to feel straightforward and comfortable. And if you’re not around the corner, no worries—I ship and work with folks from all over, and you’ll still get the same level of care.

At JR Precision, it’s not just about assembling rifles. It’s about handing you something you’ll be genuinely stoked to take to the range or the field every single time you pick it up.

“Shout out to JR Precision for chambering two Proof Research .224, 1/7, 24” for the 22 Creedmoor. Excellent work out of Lone Rock, WI. Built for the Berger, .224 70gr VLD.

“Highly recommend JR Precision LLC, I brought two rifles in to have barrels threaded for suppressors. Jason not only completed the 30-06 within a week but just in time for rifle season. It also had a zero POI change once the suppressor was installed. Everything he does is on time (or early), very precise and reasonably priced.”

“This is a excellent place to have your firearms worked on, he’s put a mount and scope on my 44 colt mag, and has put a new trigger in my Weatherby 7 mm mag, DOES PROFESSIONAL WORK, very pleased with it.”

“I have had a couple barrels threaded and also a barrel tapped for a rail on one of my handguns, everytime I get my weapon back I’m very impressed and have received them back better than expected. The attention to detail is amazing. He’s gone above and beyond every time, and reaches out every step of the way with updates or any questions that need to be addressed. I will continue to have work done by JR Precision from here on out and would recommended him to anyone needing work every chance I get.“
