The Great Lakes Firearms AR-10 .308 Win is a semi-automatic rifle built for hunters and long-range shooters who demand accuracy and reliability in a modern platform. This 18" rifle pairs a precision stainless steel barrel with a rigid billet aluminum receiver, giving you the kind of build quality that translates to tight groups and consistent performance in the field or on the range. Whether you're hunting big game, shooting metallic silhouette competitions, or working up loads at distance, this AR-10 in .308 Winchester delivers the accuracy and handling you need without fussiness.
Great Lakes Firearms engineered this rifle with attention to the details that matter: the 18" barrel features 416R stainless steel with 5R rifling, double stress-relieved and air-gauged for consistency. The 7075 aluminum upper and lower receivers are precision-machined from billet stock, and the 15.25" M-LOK rail system gives you real estate for optics, lights, or other accessories. A rifle-length gas tube and adjustable gas block let you tune the action to your ammunition, while the 0.750" gas block provides proven durability under sustained shooting.
The controls are straightforward mil-spec: a 6-position adjustable buttstock, standard polymer grip, and a trigger with a 5.5–6 lb pull that breaks clean. The muzzle is threaded 5/8x24 and hand-fitted without Loctite, ready for suppressors, brakes, or flash hiders. A fresh coat of Great Lakes Cerakote protects the finish. You'll get one 10-round magazine to get started.
This is a rifle that rewards accuracy work and holds its own whether you're pursuing whitetail, elk, or just punching paper at distance. It's the kind of gun that makes you a better shooter because it gets out of your way.
