Geissele Automatics AR-15 Standard Lower Parts Kit - Mil-Spec - No Grip, Less Trigger

The Geissele Automatics Standard Lower Parts Kit is a mil-spec component package designed to complete or rebuild your AR-15 lower receiver. Manufactured by Geissele Automatics to the same exacting standards the company applies to its complete rifles and triggers, this kit includes all of the internal small parts required to assemble a functional lower, with the exception of the trigger group and pistol grip.

This Standard LPK features 18 different part types covering the magazine catch, bolt catch, takedown and pivot pins, buffer retainer and spring, trigger and hammer springs, disconnector spring, selector detent and spring, and all remaining internal hardware needed to bring a stripped lower to life. Geissele incorporates an improved safety detent for more positive engagement of the safety selector, a meaningful upgrade over the standard mil-spec component.

This kit is sold less trigger and without a grip, allowing builders to pair it with their preferred trigger group and pistol grip. It is a direct fit for standard AR-15 / M4 / M16 pattern lower receivers and is the go-to choice for builders who want Geissele quality on the small parts while customizing the trigger and grip to taste.
