A5H2 Weight: 5.33 oz. The A5 buffer system is on of the most beneficial upgrades to the AR platform. When used in conjuction with an A5 length buffer tube, the A5 buffer increased reliability, accuracy, and performance of AR style firearms... especially in short barrel rifle and "pistol" configurations.

Important: A5 buffers are only compatible with other A5 buffer system components. The buffers themselves are longer than traditional carbine buffers, and they cannot be used in standard carbine receiver extensions.
