Description
There is a reason the Glacier keeps showing up in the packs of serious backcountry hunters. Proof Research built this rifle around one idea: shed weight everywhere possible without giving up an ounce of accuracy. This 7 PRC version starts with a Lone Peak Arms Razor stainless action, one of the smoothest running actions in the custom rifle world, and mates it to Proof's patented carbon fiber wrapped Sendero contour barrel. At 24 inches with a 1:8 twist, the barrel gives the 7 PRC cartridge room to stretch its legs, pushing heavy, high BC bullets at velocities that make cross-canyon shots on elk and mule deer feel a whole lot more manageable.
Why the Glacier Earns Its Spot on a Mountain Hunt
The stock is Proof's own carbon fiber Lightweight Mountain Hunter design finished in Tactical Flat Dark Earth, and it is bedded for consistent accuracy shot after shot. A TriggerTech trigger handles fire control with the kind of crisp, zero-creep break that makes precise shooting easier when your heart rate is up and the wind is doing its own thing. Rounds feed from a BDL-style magazine holding 4+1, and the modified ball bolt knob is easy to run fast with gloves on. Up top, a single-piece pinned rail gives you a rock solid foundation for glass.
Suppressor and Brake Ready Out of the Box
The muzzle comes threaded 5/8-24 with a thread protector installed, so you can spin on a suppressor or brake the day it arrives. That matters with 7 PRC, since a can or brake takes the sting out of a lightweight magnum and helps you spot your own hits.
A Sub 1/2 MOA Guarantee You Can Bank On
Every Glacier ships with Proof Research's sub 1/2 MOA accuracy guarantee, which is not marketing fluff. Proof cut its teeth building carbon fiber barrels that hold their point of impact through strings of fire, and that pedigree shows here. If you want one rifle that carries like a featherweight and shoots like a match gun, this is a hard combination to beat.

Frequently Asked Questions
Is the Proof Research Glacier 7 PRC suppressor ready?
Yes. The 24 inch carbon fiber wrapped barrel comes threaded 5/8-24 from the factory with a thread protector installed. That is the most common thread pitch for magnum-bore suppressors and muzzle brakes, so most popular cans and brakes will spin right on.
What is the difference between the Glacier Steel and the Glacier Ti?
This model uses a stainless steel Lone Peak Arms Razor action, while the Glacier Ti runs a titanium action to trim more weight. The steel version costs less to build and gives up very little in the field, and both carry Proof's sub 1/2 MOA accuracy guarantee. If you want the stiffest, most proven setup and do not mind a few extra ounces, the steel Glacier is the smart pick.
How accurate is the Glacier in 7 PRC?
Proof Research backs every Glacier with a sub 1/2 MOA accuracy guarantee under their test conditions. Between the carbon fiber wrapped match grade barrel, accuracy bedding in the Mountain Hunter stock, and the TriggerTech trigger, this rifle is built to hold tight groups well past typical hunting distances with quality factory match or hunting ammo.
What twist rate does the 24 inch barrel have, and what bullets does it handle?
The barrel runs a 1:8 twist, which is the standard for 7 PRC and stabilizes the heavy, high BC bullets the cartridge was designed around. Loads in the 160 to 180 grain range shoot exceptionally well, making it a great match for elk, mule deer, and open-country hunting.
