Welcome to JR Precision LLC

I grew up hunting and fishing out in rural Southern Wisconsin, where I fell in love with rifles and eventually long-distance shooting. Over time, I realized how much better it feels when you’re working with a rifle that’s not just accurate but built with care and quality. That insight pushed me toward precision—and eventually I found myself deep into tuning, tweaking, and upgrading my own gear to get things just right. These days, I’ve turned that passion into a business, helping folks dial in their own setups. Whether it’s a dependable hunting rifle or a tricked-out target build, I’m here to make sure it performs the way you want.

Just outside Lone Rock, tucked into the Driftless Area, I’ve got a little shop where things stay pretty low-key. Every build is personal, every appointment is one-on-one, and whether you just want a new barrel, a trigger swap, or a full custom rifle, I take the time to get it right. No pressure, just honest, thoughtful work.

I make it a point to really listen and understand what you’re after. It’s not just about swapping parts—it’s about building something that fits your style and shoots the way you expect. From our first conversation to the moment you take your rifle home, I want the process to feel easygoing and collaborative. And if you’re not local, that’s totally fine. I work with people from all over and make sure you get the same attention to detail.

At JR Precision, it’s not just about putting rifles together, it’s about building something you’ll feel good about every time you head out and squeeze the trigger.

“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.“
