Expo Arms H2 AR-15 Carbine Buffer with Flat Dark Earth Bumper

Nice Quality, Wish They Would Be Stamped, Works Great

MUST HAVE FOR (PISTON OPERATED UPPERS) due to higher "velocities"..
<br>
<br>Such as "Adams Arms" piston kits, etc. Prevents "LIGHT PRIMER STRIKES".
<br>
<br>
<br>Weighed compared to factory upper buffer...
<br>
<br>FACTORY....... 3.25OZ
<br>EXPO H2........ 4.50OZ

Replaced 3oz buffer with this one in my 7.5 pistol build. Runs better & such a great price I got one for my buddy too! Highly recommend . Thanks P A!

These are not stamped or marked in any way to identify them from standard weight buffers. Very disappointed in this. Color coding the bumper is meaningless, the face needs to be stamped to quickly identify it as an H/H2/H3 etc buffer without having to pull it out and weight it every time. I swap out buffers often. All other H/H2/H3 buffers have marks, why did they skip out on these?

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.

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!
