The Great Lakes Firearms AR-10 in 7mm PRC is a precision rifle built for long-range hunters and competitive shooters who demand accuracy out of the box. This semiautomatic rifle pairs a 24-inch stainless steel barrel with a tight 1:8 twist rate optimized for the 7mm PRC cartridge, delivering the velocity and consistency needed for extended-range work. The 5R rifling reduces bullet deformation and improves accuracy, while the stainless construction handles the elements without compromise.
The upper and lower receivers are machined from 7075 aluminum billet—the same alloy used in aerospace applications—providing a rigid foundation that won't flex. A 20-inch M-Lok handguard with integrated Picatinny rail gives you mounting flexibility for scopes, lights, and other accessories. The rifle system runs on a rifle-length gas tube with a heavy .750 steel gas block, ensuring reliable cycling across a wide range of ammunition while minimizing felt recoil. All internal controls—including the bolt carrier group and charging handle—are custom-designed for this platform.
The 7PRC package ships with a Hogue fixed rifle stock and standard grip, a proven ergonomic setup that works for both bench shooting and field use. You get a single-stack 5-round aluminum magazine purpose-built for Great Lakes Firearms, featuring witness holes so you can see your round count and pull-down tabs for swift loading. The muzzle brake is threaded 5/8x24 and finished in stainless steel, and the 5/8x24 threading is standard enough that aftermarket brakes are readily available if you want to change profiles.
Whether you're dialing in at the range, competing in precision rifle matches, or hunting at distance, this AR-10 gives you a modern, modular platform in a cartridge designed for flat trajectories and deep penetration. It's not a lightweight hunting rifle—it's built for the shooter who values accuracy and wants all the adjustability that the AR platform offers.

The 7mm PRC is designed as a modern, long-range cartridge, and the 24-inch barrel with optimized 1:8 twist rifling is built to deliver consistent ballistics at extended distances. Effective range depends on your load, skill, and target—we recommend checking ballistic data and practicing to find your comfort zone.
Yes. The rifle is AR-10 compatible, meaning it works with standard AR-10 lower parts kits and triggers. The rifle ships with a GLFA custom 5-round aluminum magazine, but you can use other AR-10-pattern magazines as needed.
The 20-inch M-Lok handguard features integrated Picatinny rail, giving you mounting options for rifle scopes and other accessories. You'll need to add a scope, scope mount, and rings separately—nothing is pre-installed.
The muzzle brake has a standard 5/8x24 thread, so aftermarket brakes and suppressors with that pattern will fit. Changing calibers would require a different barrel and bolt—this rifle is configured specifically for 7mm PRC.
