Aero Ar15 Fix-it-kit

The Aero Precision AR15 Fix-it-kit serves as an essential contingency solution for armorers and shooters who understand that small, high-tension components are the most likely parts to be lost or damaged during field maintenance. Whether you are performing a deep clean on a duty rifle or assembling a new lower receiver, having redundant springs and detents prevents a minor mishap from sidelining an entire weapon system. This comprehensive assortment ensures that the most critical small parts are readily available when a spring takes flight or a roll pin becomes deformed under pressure.

This kit focuses on the high-wear and high-loss components of the AR15 platform, providing multiple replacements for the most volatile small parts. It includes four takedown pin detents and springs, alongside pairs of safety selector springs, buffer retainers, and disconnector springs to maintain consistent tension and positive engagement. The inclusion of two trigger and hammer pins, as well as bolt catch roll pins, allows for the immediate replacement of hardware that may experience shear stress or finish wear over thousands of rounds.

Designed for the standard AR15 platform, the Aero Precision AR15 Fix-it-kit is a mandatory addition to any range bag or armorer's bench to ensure long-term operational readiness. The kit also features a 4-40 set screw specifically intended for receivers with threaded takedown pin holes, providing a secure alternative to traditional captured spring methods. Professionals and hobbyists alike will find this kit indispensable for maintaining specifications and ensuring that every build or repair meets strict reliability standards.
