Great Lakes Firearms
The Great Lakes Firearms AR-10 in 6.5 PRC is a purpose-built precision rifle for shooters who demand accuracy and reliability at distance. Built on a proven AR-10 platform and chambered in the hard-hitting 6.5 PRC cartridge, this rifle brings match-grade performance to long-range hunting and precision shooting. The 24-inch stainless steel barrel with 5R rifling and 1:8 twist rate is engineered for consistency, while the full-length Picatinny rail handguard gives you the flexibility to mount optics, lights, and accessories exactly where you need them.
This isn't a stock-standard AR build. Great Lakes Firearms equipped this rifle with a custom bolt carrier group and charging handle, billet aluminum upper and lower receivers (7075 for strength), and a rifle-length gas system tuned for the platform. The gas block is 4150 steel with black oxide coating—the kind of attention to detail you'd expect from a builder focused on precision. The Hogue fixed stock keeps things steady, and the included GLFA custom 5-round aluminum magazine has an open witness window and drop tabs for quick, smooth loading. Stainless steel construction throughout the barrel and muzzle brake resists corrosion and heat buildup on long shooting sessions.
Whether you're dialing in shots at the range or hunting at extended range where the 6.5 PRC excels, this rifle handles the job with confidence. The modular AR-10 design means you can swap parts, upgrade optics, and customize as your needs evolve—all while keeping a platform that's proven in the field.
