The Spike’s Tactical Gen 2 billet lower receiver (brand part no. STLB200) is engineered to shave weight and increase strength over a standard casting, coming in close to the weight of a standard forged receiver without sacrificing strength. It ships with parts included and full ambidextrous controls, and every edge and surface is 3D chamfered to reduce snagging on gear and clothing. Rated for multiple calibers, it’s a strong choice for builders who want billet strength and ambi function without the usual weight penalty. The bundled parts mean less to source separately before finishing the build.
