Seekins Precision Builders Kit Lower Parts Kit AR-15 5.56 – Black

The Seekins Precision Builders Kit Lower Parts Kit provides all the essential components needed to complete an AR-15 lower receiver build in 5.56/.223. This kit includes the trigger group, fire control parts, bolt catch assembly, magazine catch, and all necessary pins and springs—everything except the pistol grip and trigger guard. It's designed for builders who want to use their own grip and guard, or who already have those components on hand.

Manufactured from mil-spec materials with a black finish, this LPK features properly heat-treated pins and springs for reliable function. Installation requires standard AR-15 armorer's tools and basic mechanical knowledge. All parts meet or exceed mil-spec dimensions for proper fit in forged or billet lower receivers.
