The Great Lakes Firearms and Ammunition AR-10 Tungsten is a semi-automatic sporting rifle chambered in .308 Win. The direct impingement action cycles reliably with reduced recoil, and the 16-inch threaded barrel pairs well with the optic-ready flat-top receiver. The aluminum frame keeps weight at 8.6 lbs, which is reasonable for an AR-10 platform.

Features 

The Tungsten Gray Cerakote finish holds up well in wet conditions and gives the rifle a distinctive look compared to standard black. Direct impingement keeps the action smooth and follow-up shots manageable at .308 recoil levels. With the threaded barrel and optic-ready rail, it adapts well to suppressors or a variety of scope setups without modification. 
 
The .308 Win chambering makes it suitable for big-game hunting and competition shooting where the cartridge is permitted. At 16 inches the barrel is on the compact end for this platform, which trades some velocity for maneuverability.

Owners of the GLFA AR-10 Tungsten generally like what they get for the price. The Tungsten finish draws consistent praise for giving the rifle a look that stands apart from standard-black AR-10s, and most owners report solid reliability through typical range sessions.

Accuracy and manageable recoil come up often as positives, with shooters noting it handles well for both target shooting and hunting. The semi-auto action draws few complaints about its operation.

The two recurring criticisms are weight and magazine capacity. A few owners find 8.6 lbs tiring on long field carries, and the 10-round limit frustrates those used to standard-capacity AR-10 magazines. Neither issue is unique to this rifle, but they come up consistently enough to be worth knowing before buying.
