BCM MK2 Receiver Extension for AR-15
8 Position AR-15 Buffer Tube for MK2 Recoil System
BCM’s MK2 Receiver Extension is an upgrade to the standard carbine recoil assembly, that uses a specialized buffer weight. This receiver extension is around 3/4 inches longer than 6 position carbine tube, which accommodates the longer MK2 Buffer and a rifle length AR-15 recoil spring. The tube also has 8 positions – two more than the standard for adjusting length of pull.
This buffer tube also features a mil-spec diameter for your choice of buttstock. Since it’s a longer tube than usual, your stock of choice may not fully collapse. However, all mil-spec sliding stocks will fit on the tube. For a complete assembly including the buffer, spring, and this extension, check out the complete BCM Recoil Mitigation System.
Note: Do NOT use standard carbine buffer springs or buffers with this buffer tube! Doing so will impede function and may damage your components.
