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. Additional features include: an A2 flash hider, an A2 plastic grip, a single-stage trigger, and a 6-position collapsible stock. The Plus Package upgrade gives the Model 3 M4 feed ramps, 1 in 7" twist rifling, an MP/HP tested and marked bolt and barrel, an M-16 bolt carrier, a heavy buffer assembly, and one additional USGI mag.
