Designed for high ballistic efficiency, excellent wind resistance, and flat trajectories.
Ideal for western big game like elk, mule deer, and pronghorn at extended distances with appropriate bullets.
Optimized for heavy-for-caliber, high-BC bullets, giving you confident performance past traditional hunting ranges when conditions and shooter skill allow.
If you’re ready to take advantage of modern long-range cartridge design in a lightweight, high-end hunting rifle, the 7 PRC Glacier I is a top-tier option.
22" 5/8x24 Threaded Barrel – Compact, Suppressor-Ready & Field-Tuned
The 22" threaded barrel on the PROOF Glacier I 7 PRC is built to be both packable and precise:
22-inch length strikes a sweet spot between velocity and maneuverability—perfect for navigating timber, sidehills, and tight shooting positions without giving up practical long-range capability.
5/8x24 muzzle threads make it easy to install your favorite muzzle brake, compensator, or suppressor (where legal), helping reduce recoil and muzzle rise to keep you on target.
Heavy, precision-oriented profile is tuned for stability, repeatable cold-bore shots, and consistent accuracy in changing conditions.
From backpack hunts to truck-based spot-and-stalk days, this barrel is designed for real-world hunting, not just benchrest glory.
TFDE Finish – Tactical Flat Dark Earth for Real-World Hunts
The TFDE (Tactical Flat Dark Earth) finish gives this Glacier I 7 PRC a serious, modern look while also delivering practical advantages:
Flat dark earth tones naturally blend into rock, soil, brush, and high-country landscapes, helping to break up the rifle’s outline.
Low-glare finish reduces reflections that might catch the eye of sharp-sighted game at longer distances.
Pairs perfectly with today’s FDE optics, mounts, bipods, and sling gear, giving your entire setup a cohesive look.
If you want a rifle that looks like it belongs in serious backcountry and tactical environments, this TFDE Glacier I fits the role perfectly.
Lightweight, Mountain-Ready Architecture
The PROOF Glacier I series is known for delivering high-end accuracy in a lightweight hunting package:
Thoughtfully engineered to be easy to carry on long hikes, climbs, and all-day hunts.
Balanced design reduces front-end heaviness while maintaining a stable shooting platform for prone, kneeling, and supported shots.
Ideal for hunters who count ounces on their gear list but refuse to compromise on precision or reliability.
For high-country elk hunts, deep canyon deer missions, or any hunt where you earn every yard of elevation, the Glacier I 7 PRC is designed to go the distance.
Precision-Built for Consistent Accuracy
While every rifle and load pairing is unique, PROOF’s focus on precision manufacturing and premium components means this Glacier I 7 PRC is built with accuracy as a top priority:
Tight tolerances and quality control support repeatable performance and tight groups when matched with premium 7 PRC ammunition.
Designed to maintain point of impact through changing temperatures, variable positions, and real hunting conditions.
