The AR15 Armorer's Lower Parts Kit contains enough components to complete five (5) lower receivers, minus the grip. This is the easiest way to stock and sell genuine, mil-spec AR-15 parts, or use to assemble rifles on your receivers. Much lower in total cost than buying the parts one at a time. Kit contains only new, current-production, genuine, mil-spec parts; never pull-offs or direct-exchange surplus.
Armorer's Lower Receiver Parts Kit includes five (5) each of the following: Trigger spring, trigger pin, hammer spring, hammer pin, disconnector and spring, bolt catch, bolt catch plunger, bolt catch spring, bolt catch roll pin, selector, selector detent, selector detent spring, takedown detent sets and springs, pivot pin, rear takedown pin, buffer retainer and spring, magazine catch, button and spring, screw and washer, triggerguard assembly and pin, a mil-spec trigger, and hammer.
