Overview
The Aero Precision AR-15 Mil-Spec Carbine Receiver Extension is a tube-only assembly designed to meet military specifications, ensuring compatibility with a wide range of carbine stocks. This Mil-Spec buffer tube is essential for proper cycling in your AR-15 build, as it accommodates a carbine-length gas system, which is often preferred for its balance of recoil management and reliability. Builders frequently use this receiver extension in Mid-Length gas system configurations chambered in 5.56 NATO.
