Stag Arms builds this pistol around a forged 7075-T6 aluminium receiver set, protected by Type III hard-coat anodizing. The lower bears the Wyoming roll-mark used after the company’s 2019 relocation, confirming recent production.
The 8-inch, 1:7-twist barrel is crafted from chrome-moly vanadium steel, treated with QPQ nitride inside and out, and cut with 5-R rifling for consistent performance with both subsonic and supersonic loads. Threads are 5/8-24 and host the installed VG6 Precision Gamma 300 BLK muzzle brake, which mitigates recoil and muzzle rise.
Controls are fully ambidextrous: a bilateral safety selector complements the Aero Precision Breach charging handle, making manipulation straightforward for left- or right-handed shooters. The single-stage trigger offers a familiar, crisp break.
A 7-inch Stag SL free-float M-LOK handguard keeps weight forward of the receiver minimal while providing plenty of attachment real estate. A dedicated 300 BLK-marked PMAG reduces the risk of caliber mix-ups and feeds the pistol’s 30+1-round capacity.
