Armaspec SPR Light Lower Parts Kit – AR-15/M16 (5.56/.223)

The Armaspec SPR Light Lower Parts Kit provides all the essential components needed to complete an AR-15 or M16 lower receiver build. This kit includes the trigger assembly, hammer, disconnector, springs, pins, and all necessary small parts to make your stripped lower fully functional. Designed for standard mil-spec lower receivers chambered in 5.56 NATO or .223 Remington, this kit is ideal for builders looking for reliable, factory-specification components without unnecessary extras.

All parts are manufactured to mil-spec dimensions with a black finish for corrosion resistance. Installation requires basic armorer knowledge and standard AR-15 tools including pin punches and a hammer. Some builders may prefer a specialized trigger pin installation tool for easier assembly. Does not include fire control group springs or grip hardware—verify your specific build requirements before installation.
