Great Lakes Firearms
The Great Lakes Firearms AR-10 7PRC in 24" with OD Green and stainless steel is purpose-built for long-range hunters and precision shooters who demand serious performance in a semi-custom platform. This 7PRC bolt rifle combines the proven AR-10 ergonomics shooters know with caliber selection and barrel quality that deliver consistent accuracy at distance. If you're running a precision rifle for hunting or competition, this GLF build gives you factory-level reliability with thoughtful component choices that matter in the field.
The barrel is the heart of any rifle, and Great Lakes Firearms spec'd this one right: 24 inches of 416R stainless steel with 5R rifling and a 1:8 twist rate engineered for the 7PRC cartridge. The matching muzzle brake (5/8 x 24, also 416R stainless) keeps things corrosion-resistant and threads directly to your barrel. The billet aluminum upper and lower receivers (7075 aluminum—the good stuff) provide the rigid platform precision shooting demands, and the rifle-length gas system is tuned for consistent cycling and reliability.
This isn't a bare bones build. The 20-inch M-Lok handguard with integrated Picatinny rail gives you modern mounting options for glass, lights, or shooters' aids. The gas block is 4150 steel with black oxide coating, the Hogue fixed stock provides solid cheekweld and repeatability, and the custom BCG and charging handle are designed specifically for this platform. The included 5-round magazine is aluminum with an open witness window and pull-down tabs—practical touches that show this rifle was assembled by people who actually shoot.
Whether you're reaching out on distant game or running precision validation at the range, the AR-10 platform's lower-third controls and modular layout make this a rifle you'll keep running. The 7PRC delivers ballistic performance in a proven action, and GLF's attention to component quality means less troubleshooting and more time behind the trigger.
