BCM MK2 Receiver Extension (Buffer Tube) – A5 Compatible

The BCM MK2 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.

The BCM Intermediate Receiver Extension, designed for use with A5 systems, aids in lowering bolt carrier velocity, reduces cyclic rate, and softens felt recoil increasing overall reliability and performance.

This receiver extension tube can also be utilized as a replacement receiver extension for the AR-10 rifle.
