The heart of this build is a Wilson Combat WC-15 lower receiver with an oversized beveled mag-well for smoother, faster reloads. The “WCA” serial prefix denotes post-2019 manufacture, ensuring current-spec machining and metallurgy.
A forged flat-top upper receiver carries a 16" 5.56 NATO barrel secured by a low-profile mid-length gas block. The dual-baffle side-ported muzzle brake and mid-length gas system work together to soften recoil and keep the rifle flat during rapid strings.
The Aero Precision ATLAS S-ONE 15" free-float handguard uses a slim clamping system that aligns perfectly with the upper receiver. Full-length Picatinny rail up top and M-LOK slots along the sides and bottom give ample real estate for optics and accessories while keeping weight down.
Magpul furniture finishes the rifle: a six-position MOE SL stock in grey and a rubber over-mold MOE+ grip provide a solid, ergonomic interface. An aftermarket flat-bow trigger shoe delivers a crisp, consistent break for precise shot control.
The 1/2-28 threaded barrel accepts standard suppressors or flash hiders, and the rifle ships optic-ready with no sights installed. Four magazines, rail covers, hand stop, and a QD sling round out a turnkey package that’s ready for range or duty from day one.
