The Radical Firearms 16″ Big Bore Contour .350 Legend AR rifle pairs durable MIL-STD forgings with a 15″ MHR free-float rail to deliver a dependable, accessory-friendly platform. Built around a 16″ 4140 chrome-moly vanadium big-bore contour barrel (Melonite finished) and a carbine-length gas system, this model offers a robust but lightweight fighting-rifle feel. Forged 7075 T6 upper and lower receivers, an M4 MIL-STD upper with oversized ejection port, low-profile gas block, A2 flash hider, and B5 Bravo stock with a 6-position buffer tube make the rifle adaptable for hunting or range use. The 15″ M-LOK hybrid rail keeps the barrel cool while providing ample real-estate for optics, lights, and grips.
