Armaspec SPR LT Lower Parts Kit – AR-15/M16 (FDE)

The Armaspec SPR LT Lower Parts Kit provides all the essential components needed to complete an AR-15 or M16 lower receiver in Flat Dark Earth. This kit includes the trigger assembly, hammer, disconnector, selector, magazine release, bolt catch, and all necessary pins and springs—everything except the pistol grip and trigger guard. It's designed for builders who want a straightforward, mil-spec parts kit to get their lower operational without extras they may already have.

All components meet mil-spec dimensions for drop-in installation in standard AR-15/M16 lower receivers. The FDE finish is applied to external controls for a coordinated appearance. Installation requires basic armorer tools—hammer and pin punches—and familiarity with AR-15 assembly procedures. No gunsmithing required, but attention to proper spring orientation and pin alignment is essential.
