Assembled in Charleston, South Carolina, with high-quality materials and workmanship…delivering All-American hardware at an unbeatable value. The upper receiver is forged from 7075-T6 aluminum, the hardest and most durable material of any upper, then Mil-Spec Type III hard-coat anodized.

The barrel is made from 4150 chrome moly steel, and features phosphate coating to increase durability and reduce wear. The 15" Keymod handguard is made from aircraft-grade aluminum, and free-floated for maximum accuracy. It's a nice start to your build…that's also USA-made and super-affordable. Can't go wrong here.
