Ratings & Reviews
Recommended upgrade for Carbine length Gas AR's
by Oregon Shooter -
I recently got a Carbine length gas AR and it has a significant feeling of jarring when shooting, so I tried this H2 buffer, and the quality is excellent, works great, reduced felt "jolt" in the recoil, functions just fine, brass ejects about 2:30 to 3:30 now depending on the load.
Great H2 weight buffer, stamped mine H2...
by Ralph -
The color coding of the bumper doesn't work for me so I took a small number stamp set I have & lightly stamped a number "2" into the face of the buffer to more easily ID it as an H2. Looks to be comparable to other manufacture's offerings costing twice as much. Wish I had picked up a few more while they were on sale.
EXPO ARMS H2 BUFFER

It works as intended
It's an H2 Buffer
by JD -
Run this in a 5.56 middy AR and it smoothes out recoil (as if there was much). No issues with low power Wolf steel ammo either. Front face is not stamped with an "H2". I don't switch out buffers, therefore the color code system used by Expo Arms is a non-issue for me.
Great buffer at a reasonable cost.

Works great! Tamed the recoil impulse down on my overgassed pistol. Took a marker and wrote H2 on the side and etched H on top.
Works good for my 10.5 upper
I ordered this and the discounted buffer spring. Both arrived carefully packaged and in perfect condition. Fast shipping and the best prices.

Nice Quality, Wish They Would Be Stamped, Works Great
MUST HAVE FOR PISTON UPPERS!
by Adam -
MUST HAVE FOR (PISTON OPERATED UPPERS) due to higher "velocities"..
<br>Such as "Adams Arms" piston kits, etc. Prevents "LIGHT PRIMER STRIKES".
<br>Weighed compared to factory upper buffer...

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!
Not marked with H2
by Mike -
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?
From not functioning to 100 percent function
by Stanton -
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!
