Aero Precision AR-15 Lower Parts Kit (No Fire Control Group) – AR-15 Platform

The Aero Precision AR-15 Lower Parts Kit provides all the essential small parts needed to complete a stripped AR-15 lower receiver—minus the fire control group. This kit is ideal for builders who already have a preferred trigger assembly or plan to purchase one separately. It includes the magazine release, bolt catch, selector components, pivot and takedown pins, trigger guard, and all necessary springs and detents for a complete lower build.

Constructed from mil-spec materials with a black oxide finish on steel components, this kit meets USGI specifications for fit and function. Installation requires basic armorer tools and attention to detail when managing small springs and detents—builders should work in a contained area to prevent loss of parts. A punch set, hammer, and lower receiver vise block are recommended for proper assembly.
