Great Lakes Firearms AR-10 .308 Win 18" Tungsten/SS 10-Round Rifle

The Great Lakes Firearms AR-10 .308 Win is a semi-automatic rifle purpose-built for hunters and precision shooters who demand reliability and accuracy without compromise. Built on a billet aluminum upper and lower receiver, this .308 Winchester rifle combines the proven AR platform ergonomics with the terminal energy needed for big game at distance. The 18-inch barrel with 5R rifling and 1/10 twist delivers consistent accuracy, while the rifle-length gas system keeps recoil manageable for follow-up shots—whether you're hunting whitetail at 200 yards or working steel at the range.

The tungsten-finished receiver and stainless steel barrel showcase Great Lakes Firearms' attention to durability and corrosion resistance. A full 15.25-inch M-LOK rail gives you genuine modularity to mount optics, lights, and accessories exactly how you want them. The muzzle is threaded 5/8x24 for suppressors or brakes, and comes hand-fitted without Loctite for easy future adjustments. The included mil-spec six-position adjustable stock and polymer grip ensure comfortable shooting for most body types and shooting styles.

This is a rifle that works equally well whether your mission is hunting season preparation or competing in metallic silhouette events. The single 10-round magazine keeps you compliant where it matters while the mil-spec 5.5–6 lb trigger breaks cleanly and predictably. With proper optics and ammunition, the AR-10 .308 delivers the accuracy hunters expect at distance and the reliability shooters demand when it counts.
