A Passion of Precision
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.

Pricing
Barrel Chambering and Fitting to your action:
$350.00 Standard cartridges up to .338
$400.00 .338 cal and larger (includes Smokeless Muzzleloader)
Prices listed are for customer supplied barrels.
The barrel is the most critical component influencing rifle accuracy. At our shop, we prioritize delivering chambers of the highest precision. The chamber throat is indicated to 0.0001″ runout relative to the bore centerline, achieving optimal concentricity for the projectile’s transition into the rifling. Alignment is performed by taking direct measurements from the lands and grooves of the bore itself, avoiding tolerance stacking associated with alternative methods. Additionally, we take meticulous care to avoid gripping or supporting the barrel in any manner that could induce stress or deflection during machining. Our chambering procedures and optimized sequence of operations are designed to produce the straightest and most accurate barrels possible.
Action Truing:
$375.00
True action face, threads, true and lap lug faces.
Muzzle Threading:
$150.00 standard threads
$175.00 for brake timing/indexing
$30.00 Custom Thread Adaptor (i.e. 1/2×28 to 5/8×24)
Muzzle threads are single point cut after the bore of the barrel has been dialed in to at least .0002″ coaxial to the bore’s centerline. This ensures your projectile will pass perfectly down the centerline of your muzzle brake or silencer.
Brake timing, also referred to as brake indexing, is a procedure used to precisely align (or “index”) a directional muzzle brake on a firearm barrel. This ensures that the vented ports or gas redirection features are oriented in the correct direction, allowing exhaust gases to be expelled in a controlled manner. Proper timing prevents unintended asymmetric gas forces that could impart unwanted torque, muzzle rise, or lateral shift, thereby minimizing adverse effects on recoil direction and point-of-impact consistency.
We use thread micrometers to guarantee fitment of your muzzle accessories.
Stock Bedding:
$125.00 Standard bedding
$175.00 Pillar bedding
Stocks are bedded using stress-free techniques to eliminate deflection and ensure a flawless fit for the barreled action.
Trigger installs:
$50 + price of trigger
Other Machining work not listed:
$125.00/hr.
As a one-man shop, I take great pride in personally handling every aspect of your precision rifle build—from the machining work to final assembly. The core of my services focuses on chambering and fitting barrels to actions, bedding stocks, and complete rifle assembly.
That said, I frequently receive inquiries about additional services that I place in a “other” category. Please understand that any work not listed or directly quoted will fall under “other” and be charged an hourly shop rate of $125.00/hr.
Shipping:
All shipping charges will be added to the final price of a completed job. A hard case will be purchased (60.00 +/-) and used for shipping. You are welcome to use your own case.

What Our Clients Say
“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.
Frank S.
“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.”
Justin O.
“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.”
Bob S.
“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.“
