Model: 140635 • Caliber: 7mm PRC • Thread: 5/8x24 • Finish: Black Granite (BGR) • UPC: 843068140635
Built for serious hunters who live in steep country and demand match-grade precision, the PROOF Glacier Steel 7PRC 22 8 5/8-24 BGR (140635) combines a world-class steel action, PROOF’s sendero-contour carbon fiber barrel, and an ultra-light carbon stock into a mountain rifle that still shoots like a true long-range precision rig. Chambered in 7mm PRC with a 22" 1:8 twist threaded barrel, this Glacier Steel delivers flat trajectories, excellent wind performance, and reliable terminal ballistics on big game at extended distances—without weighing you down on the hike in.
Purpose-Built 7mm PRC Backcountry & Long-Range Hunting Rifle
The 7mm PRC chambering is built from the ground up for modern long-range hunting and precision shooting, and PROOF’s Glacier Steel takes full advantage of it:
Optimized for high-BC 7mm bullets, giving excellent retained velocity and wind resistance for ethical shots in big Western country.
22" barrel keeps the rifle compact in the timber or in and out of trucks and blinds while still providing excellent performance with modern propellants in 7 PRC.
Bolt-action, right-hand configuration with a smooth, fast cycling stroke for follow-up shots when needed.
If your hunts take you up scree slopes, across ridges, and into the alpine, this Glacier Steel is designed to ride on your shoulder all day and still deliver when the crosshairs settle.
Lone Peak Arms Razor Steel Action – The Rifle’s Foundation
At the heart of the Glacier Steel 7PRC is the Lone Peak Arms Razor steel action, one of the most respected custom-grade actions on the market.
Precision-machined steel receiver for strength, repeatable lock-up, and long-term durability in harsh backcountry conditions.
Designed to interface perfectly with PROOF’s bedding system and carbon stock for consistent harmonics and accuracy.
Paired with a TriggerTech match-grade trigger that offers a crisp, consistent break and minimal over-travel, helping you call every shot even when you’re winded or shooting from improvised mountain rests.
This action/trigger combo brings custom-rifle refinement to a turn-key factory package.
22" PROOF Sendero Carbon Fiber Barrel – 1:8 Twist, Threaded 5/8x24
The Glacier Steel is all about maximizing performance while minimizing weight, and the barrel is where PROOF’s technology really shines:
22" PROOF sendero-contour carbon fiber barrel, match-grade, built around a stainless steel core and wrapped in PROOF’s advanced carbon layup.
1:8" twist rate, ideal for stabilizing today’s long, heavy 7mm projectiles you’ll run in 7mm PRC for long-range hunting and steel.
Threaded 5/8x24 at the muzzle for easy installation of brakes or suppressors; the Glacier Steel ships threaded and typically includes a thread protector.
PROOF’s carbon-wrapped barrels are known for maintaining accuracy as they heat, shaving weight compared to steel profiles while still giving the stiffness and consistency serious shooters demand.
Carbon Fiber Lightweight Mountain Hunter Stock – Black Granite (BGR)
To keep the rifle truly “Glacier-light,” PROOF pairs the action and barrel with their carbon fiber Lightweight Mountain Hunter stock, finished here in Black Granite (BGR).
Full carbon fiber construction for excellent strength-to-weight ratio and long-term durability in wet, cold, and rough backcountry conditions.
Black Granite finish offers a dark, speckled pattern that blends into rock, timber, and shadowed alpine terrain while still looking high-end on the bench.
Designed with an ergonomic, hunting-focused profile that shoulders quickly, tracks naturally, and balances well with a lightweight optic.
You get the look and feel of a custom carbon hunting rifle with the confidence that it’s built to handle years of hard use.
Sub 1/2 MOA Accuracy Guarantee
One of the most compelling features of the Glacier Steel series is PROOF’s SUB 1/2 MOA accuracy guarantee.
Factory-backed guarantee that the rifle will produce sub-0.5 MOA 3-shot groups at 100 yards with quality match or premium hunting ammunition and a capable shooter.
Supported by an extreme-accuracy bedding system that locks the action into the carbon stock for consistent point-of-impact and repeatability.
This isn’t just a light rifle that’s “good enough” for the woods; it’s a precision tool that happens to be built for the mountains.
BDL-Style Magazine, 4+1 Capacity & Field-Ready Features
The Glacier Steel 7PRC is configured as a serious hunting rifle from muzzle to buttpad:
BDL-style internal magazine with 4+1 capacity in 7mm PRC, giving you four in the magazine plus one in the chamber—plenty for big-game hunts without adding the bulk of a detachable box mag.
Bolt-action safety and ergonomics configured for hunting use, with a right-hand orientation that cycles smoothly and instinctively.
Overall rifle weight typically around 6.7–6.8 lbs bare, which is impressively light for a full-size 7 PRC with a sendero contour barrel and steel action.
Load it with a quality optic and a lightweight sling, and you’re still in very manageable territory for all-day mountain hunts.
