    BCM A5 Buffer Extension

    Used the extension for my LR-308 rifle. Smooths out the recoil impulse on my rifle. Allows me to use a standard carbine buffers. Shipped fast. I ordered another extension and buffer to update my .224 Valkyrie to also give it a smoother action while firing. Both rifles have a rifle length gas system and I feel the A5 system makes it more comfortable to shoot them.

    Fast excellent service quality parts you can depend on I ordered this to replace my carbine buffer system on my 12.5" build and it's amazing. If you've ever wondered about switching to the A5 BUFFER system well worth it.
    BCM is one of my goto companies for AR parts
