The Expo Arms H2 Carbine Buffer is an easy and inexpensive upgrade for your AR-15. Whether your rifle is over gassed or you're simply looking to reduce felt recoil, a 4.6 oz heavy buffer can be a significant improvement over the standard AR-15 carbine buffer. These buffers feature a machined aluminum body with a durable black hardcoat anodized finish and flat dark earth rubber bumper to dampen recoil.

This 3.25" buffer is compatible with AR-15 MIL-SPEC and Commercial spec receiver extensions or 8" GI-spec AR-10/AR-308 receiver extensions.

From not functioning to 100 percent function

by -

This was just the fix I needed to get my echo trigger and new build running properly in my 7.5 ar pistol in 556. No more failure to feed or fire. The pistol went from not function what so ever to 100 percent function thanks to this buffer! So highly recommend for certain builds if you need this weighted buffer.

Works perfectly fine compared to other high dollar brands.

Great service


Used this to replace my 3oz. buffer in my sig m-400. Functions flawlessly with reduced recoil and back on running coyotes faster. Shipping only took 2 days. Outstanding job PA 2 thumbs way up!
