PROOF Research Carbon Fiber PXT Barrel
Take advantage of the latest PROOF Research Carbon Fiber PXT technology. Its innovative delayed-twist rifling design gradually increases the twist rate through the barrel, helping reduce initial bullet stress, minimize felt recoil, and promote longer barrel life.
Combined with lightweight carbon fiber construction, the PXT barrel is an excellent option for hunters and precision shooters who want to manage rifle weight without overlooking performance.
Every barrel is custom chambered in-house by SJA, with careful attention to chambering precision and fit.
Precision Action & Chambering
Choose from three proven action options: Kelbly Nanook, Falkor LW7, or Impact NBK.
The rifle starts with a 416R stainless steel billet foundation. A fluted bolt and mechanical ejection help deliver smooth, efficient operation.
SJA chambers every rifle we build, with a focus on precision, consistency, and reliable performance.
Custom Stock & Bedding
The Manners LRH Adjustable Stock offers an adjustable fit for your shooting position and preferences. Its carbon fiber construction keeps weight to approximately 28 ounces.
We use Devcon bedding to properly secure the action and create a consistent foundation. The barrel channel allows the carbon fiber barrel to free-float without obstruction.

Timney Elite Hunter: Included as a standard option.
TriggerTech Diamond: Available as an upgrade for shooters looking for a premium trigger option.

Just got mine! I had a 22” 300PRC built! This thing is a hammer! And it’s so lightweight. I had a comp rifle built by these guys last year and this new one is just as accurate and none of the weight to pack around!
Brandon watson –
Not to brag, but mine is the one in the picture! Lol
18” 6.5PRC and this thing has been an absolute nightmare for mule deer and speed goats!
If you’re looking for a lightweight carbon fiber hunting rifle that handles like your heavy duty old school tactical rifle this is for you!!!!

Okay, so the wait time killed me! This is my first custom rifle. I normally buy off the shelf but higher end, like a fierce or CA. I was very skeptical spending over 5k on a rifle. Cole helped me make the choices on barrel length, and what to chamber it in based on a lengthy conversation about what and where I hunt. At the end of the day, my skepticism turned to being blown away. Just putting this rifle in your hand will empress you! Every detail, over ever inch of this rifle is well thought out and planned. These are not one size fits all, these are build just for you! This is by far the most comfortable packing, and best shooting rifle I own. Highly recommend!!!!
