The Spikes Tactical Lower Parts Kit (brand part number SLPK101) gives you every small part needed to finish out a stripped AR-platform lower receiver in one box, built to exceed military specifications in both materials and fit and finish. It includes a rounded hammer that works across calibers, hammer and trigger springs, a trigger with disconnector and springs, a safety selector with detent and spring, a bolt catch with spring, a magazine catch with spring and button, front pivot and rear takedown pins, and an aluminum trigger guard with a spring-loaded detent and roll pin. The hammer and trigger pins are stainless steel with a black oxide finish rather than standard mil-spec steel, and a complete A2 pistol grip with hex screw and star lock washer rounds out the kit. Everything is made in the USA.
