Great Lakes Firearms AR-10 .308 Win 18" Stainless

The Modern Sporting Rifle for Big Game and Long-Range Shooting

The Great Lakes Firearms AR-10 represents a thoughtful approach to the modern rifle platform, chambered in the venerable .308 Winchester. This is a rifle built for serious work—whether that work involves harvesting game or ringing steel at distance.

Barrel and Accuracy

The heart of any rifle is its barrel, and Great Lakes has invested considerable effort here. The 18" stainless steel barrel features:

• 5R rifling for superior bullet stability and reduced fouling
• Double thermal stress relief to ensure dimensional stability across temperature extremes
• Air-gauged for quality assurance
• 1/10" twist rate optimized for .308 Winchester ballistics
• Nitride coating for corrosion resistance and durability

Receiver and Controls

The rifle features billet upper and lower receivers machined from 7075 aluminum, the same material used in aerospace applications. This ensures rigidity without unnecessary weight. The controls are Mil-spec throughout: adjustable buttstock, polymer grip, and a crisp trigger with a 5.5 to 6-pound pull.

Ergonomics and Modularity

The 15.125" M-LOK handguard provides ample real estate for mounting optics, lights, and other accessories. A Picatinny rail sits atop the upper receiver for primary optic mounting. The rifle-length gas tube and 0.750" gas block ensure reliable cycling across a wide range of ammunition.
