Armaspec SPR Light Gun Builder's Kit – AR-15

The Armaspec SPR Light Gun Builder's Kit provides essential lower parts for completing an AR-15 build with a focus on reduced weight and smooth operation. This kit includes the fire control group, trigger pins, magazine catch assembly, bolt catch assembly, takedown pins, pivot pin, and selector components—everything needed for a functional lower receiver except the pistol grip and buttstock assembly. It's designed for builders who want proven parts with a lighter profile compared to standard mil-spec components.

Manufactured from heat-treated steel and aluminum alloy with a black finish, these parts are engineered for reliable cycling and long service life. Installation is straightforward for anyone with basic AR-15 assembly experience and standard armorer's tools. All pins and springs are included.
