Stag Arms was founded with the goal to manufacture reliable, 100% American made, competitively priced mil-spec ARs, quickly becoming a market leader and one of the largest firearms manufacturers in the United States. Their Model 3 is endlessly customizable with a full-length picatinny top-rail, a railed gas block, and a Diamondhead VRS drop-in modular handguard. It's made to Mil-Spec requirements with forged aluminum upper and lower receivers and a 16", 4140 steel, chrome-lined, government profile, manganese phosphate coated barrel. The 3T-M variant adds Diamondhead aluminum flip-up front and rear sights, a Magpul ACS 6-position buttstock, and a Magpul MOE grip. Additional features include: an enhanced bolt carrier with a manganese phosphate coating, an A2 flash hider, and a single-stage trigger.
