Beef up your AR with the intermediate length buffer system known as the A5! Perfect for almost every AR15/M16/M4 variant. Originally contracted on request from the United States Marine Corps to help enhance the ergonomics and length of pull issues of the M16A4’s, it was paramount that it kept the reliability of the rifle buffer system. The A5 not only accomplished the USMC goals, it also added extra benefits to the buffer system. In short, the A5 gives your AR the smoothest, most efficient and consistent cycling possible from your recoil system.


The RE-A5 Receiver Extension is a 7-position receiver extension tube designed to work with the VLTOR A5 buffer system. This receiver extension is slightly longer than the traditional M4 receiver extension and is designed to work with Mil-Spec dimensioned M4/AR-15 type collapsible stocks. This receiver extension tube can also can be utilized as a replacement receiver extension for the AR-10 rifle.


A5 receiver extension (buffer tube) machined from 7075-T6 and manufactured to Mil-Spec dimensions and specifications. Mil-Spec receiver extensions have a slightly smaller dimension where the stock slides on.
