Great Lakes Firearms Ar-10 6.5Prc 24 Odg/Ss 5Rd

The Great Lakes Firearms AR-10 in 6.5 PRC is a purpose-built long-range rifle engineered for serious hunters and precision shooters who demand accuracy at distance. Built on a 7075 aluminum billet lower and upper receiver, this AR-10 combines a 24-inch stainless steel (416R) barrel with 5R rifling and a 1:8 twist rate optimized for the 6.5 PRC cartridge—a proven performer for extended-range hunting and target work. This is a rifle that bridges the gap between off-the-shelf convenience and custom precision.

The stainless barrel resists corrosion in field conditions, while the integral 5/8 x 24 muzzle brake (also stainless 416R) manages recoil and helps you spot your shot. The rifle-length gas system and custom bolt carrier group work together to cycle cleanly and reliably, supported by a .750 4150 steel gas block finished in black oxide. The 20-inch aluminum M-Lok handguard with integrated Picatinny rail gives you genuine modularity—mount optics, lights, or other accessories exactly where you need them without compromise.

For ergonomics, you get a Hogue fixed rifle stock and standard grip that won't fight you during long shooting sessions or a day in the field. The included GLFA custom aluminum 5-round magazine features an open witness window so you know your round count at a glance, plus removable tabs that make reloading simple and fast. Everything here is designed to work, not distract.

This is the kind of rifle you build once and trust completely—whether you're dialing in at the range or preparing for a serious hunt where 500+ yard shots are part of the plan.
