CMMG AR-15 Gunbuilder Lower Parts Kit Without Grip/Fire Control

The CMMG Gunbuilder Lower Parts Kit is a set of small mil-spec components for building an AR-15 lower receiver in the 5.56x45mm NATO caliber. It supplies the minor internal parts such as the bolt catch, magazine catch, selector, takedown pin, pivot pin, and trigger pin, so a builder does not need to buy parts that may go unused.

The kit is intended to leave room for customization. Pistol grip, trigger and hammer, disconnect, trigger guard, and related springs are not included, so the builder can select those separately, including aftermarket match-grade trigger components.

The kit is finished in black and is designed to fit a standard mil-spec AR-15 lower receiver.
