Description
Big magnum performance in a rifle you can carry up a mountain without regretting it. That is the whole idea behind the Proof Research Elevation MTR, and this .300 PRC version with a 20 inch barrel might be the most practical take on it yet. MTR stands for Mountain Tactical Rifle, and it splits the difference between a precision rig and a lightweight hunting rifle better than most guns that try. You get a stock with a raised comb and near vertical grip that feels at home behind a bipod, without the weight penalty that usually comes with that kind of setup.
What Makes the Elevation MTR Different
The heart of this rifle is Proof's patented carbon fiber wrapped, match grade barrel in a Sendero contour. It runs a good bit lighter than a steel barrel of the same profile and sheds heat faster, so your point of impact stays put through longer strings. The 1:9 twist stabilizes the heavy, high BC bullets the .300 PRC was designed around, and the muzzle comes threaded 5/8×24 with a thread protector, so adding a brake or suppressor takes minutes. That 20 inch tube also keeps overall length sane once a can goes on, which matters more than people think on a magnum.
Proven Parts Behind the .300 PRC
Proof did not cut corners on the rest of the build. The Zermatt Arms Origin action is one of the most respected in the custom rifle world, running smooth with a Remington 700 footprint, and it is paired with an adjustable TriggerTech trigger that breaks clean every time. A one piece pinned rail is ready for your optic, the detachable box magazine holds three rounds of .300 PRC, and the modified ball bolt knob gives you plenty to grab with gloves on. Every rifle is test fired before it ships and carries Proof's sub-MOA accuracy guarantee. The TFDE finish on the carbon fiber stock rounds it out with a look that hides well in the field and holds up to hard use. For elk, mule deer, or steel way out past where most rifles get boring, this one earns its spot in the truck.

Frequently Asked Questions
Is a 20 inch barrel long enough for .300 PRC?
You will give up some velocity compared to a 24 or 26 inch tube, but the .300 PRC still carries plenty of energy for elk and other big game at practical hunting distances from a 20 inch barrel. The trade is worth it for a lot of hunters, since the shorter barrel handles better in timber and keeps overall length reasonable with a suppressor attached. The 1:9 twist still stabilizes the heavy match style bullets the cartridge is known for.
Can I suppress the Elevation MTR 300 PRC?
Yes, the muzzle comes threaded 5/8×24 with a thread protector installed, which is the standard thread pitch for most 30 caliber suppressors and muzzle brakes. The 20 inch barrel was clearly chosen with a can in mind, since the finished length stays manageable even with a full size suppressor mounted.
What action does the Proof Elevation MTR use?
It is built on the Zermatt Arms Origin action, a favorite in the custom rifle world known for smooth cycling and consistent headspacing. It uses a Remington 700 footprint, so aftermarket support for stocks, triggers, and mounts is about as broad as it gets. Proof pairs it with an adjustable TriggerTech trigger from the factory.
How accurate is this rifle out of the box?
Every Elevation MTR is test fired at the factory and backed by Proof Research's sub-MOA accuracy guarantee. Owners regularly report tighter groups than that with quality factory match ammo. The carbon fiber wrapped barrel also dissipates heat better than solid steel, which helps groups stay consistent through longer range sessions.
