Overview

The Aero Precision Lower Parts Kit without Fire Control Group is specifically designed for builders who plan to install an aftermarket trigger system. This kit eliminates the redundant mil-spec trigger components, allowing you to invest those savings into a premium trigger of your choice while still providing all the essential small parts needed to complete your lower receiver.

Aero Precision is known for their quality control and tight manufacturing tolerances, ensuring that every component in this kit meets or exceeds mil-spec standards. The kit includes all takedown pins, springs, detents, bolt catch assembly, magazine catch, and safety selector - everything except the trigger, hammer, and disconnector. This makes it the perfect companion for Geissele, LaRue, CMC, or any other aftermarket trigger system.

By omitting the fire control group, builders avoid paying for components they'll never use while maintaining the same Aero Precision quality found in their complete kits. This approach is both economical and practical, especially for those building duty rifles, competition guns, or precision platforms where a premium trigger is essential to the build's purpose.
