A slick-side upper receiver eliminates the forward assist for a clean profile and reduced weight, while the 15" 6061-T6 aluminum M-LOK handguard provides continuous 12-o’clock Picatinny rail space for optics or sights.
The 16" barrel is chrome-lined, threaded 5/8-24 UNE-2A, and paired with a carbine-length gas system for reliable cycling across suppressed or unsuppressed .300 BLK loads. A 1:7" right-hand twist stabilizes both subsonic and supersonic projectiles.
Controls are enhanced with a polished nickel-Teflon single-stage trigger for a smooth break, and an A2-style polymer pistol grip for familiar ergonomics. The Mission First Tactical Battlelink Minimalist six-position stock keeps overall weight low and offers a 10.6" length of pull at its shortest setting.
Both upper and lower receivers are forged from 7075-T6 aluminum and finished in durable black hard-coat anodizing. Factory “Don’t Tread On Me” engraving featuring the coiled Gadsden snake underscores the rifle’s patriotic theme and limited-edition status.
