Great Lakes Firearms AR-10 .270 Win Sniper Rifle - Gray/Stainless Steel

The Great Lakes Firearms AR-10 .270 Win is a purpose-built long-action rifle that brings modern AR ergonomics and modularity to a proven hunting and long-range cartridge. Built on a billet aluminum platform with a 24-inch stainless steel barrel, this rifle delivers the accuracy and reach serious hunters and riflemen demand—without the weight penalty or complexity of a traditional bolt gun. At 9.25 lbs and 45.50 inches overall, it's built to be carried and shot all day.

.270 Winchester has been a go-to for hunters crossing open country and taking shots at distance for decades, and the GL10 LA platform channels that legacy into a modern, AR-compatible platform. The 5R rifling and 1:10 twist barrel are engineered for both accuracy and velocity, while the rifle-length gas system keeps recoil manageable without sacrificing reliability. The 5/8 x 24 muzzle brake helps tame the .270's signature kick, making extended shooting sessions more comfortable and follow-up shots faster.

This is a working rifle, not a range queen. The 20-inch M-Lok upper rail gives you full flexibility to mount optics, lights, and accessories your way. The Hogue fixed stock and mil-spec trigger provide a solid, predictable platform, while the custom BCG and charging handle are tuned to the GL10 platform. It ships with a 5-round magazine, and the lower is AR-10 compatible, so you can swap in aftermarket lower parts kits or alternative triggers if you want to customize further.

If you hunt big game at distance, run long-range precision drills, or just want the flexibility and modularity of an AR in a serious hunting cartridge, the .270 Win AR-10 splits the difference between tradition and modern rifle building.
