really like this line of buffers

by -

Decided to build a 458 Socom with PA barrel, BCG, & Upper... Initial test fire showed some opportunities.... the first thing I noticed was the need for a different buffer, I chose this H3 and it worked miracles.... definitely will order again.

Does the job

Good and basic for the price. Been needing it to tame a overgassed upper with a fixed A2 fsb. It solved the malfunctions but the upper is still overgassed, however I’m happy that the AR no longer jams thanks to this H3 buffer.

Out weighs the compotition

I purchased both Expo Arms H3 and different T3, the Expo Arms actually weighed more than the other T3 even though it was supposed to weigh less.H3 5.58 oz.,T3 5.38,cheaper Expo Arms better deal.

The right buffer

This what I needed to fix and jamming issue. I'm 100% satisfied with the buffer and with The company

This is the best thing I've done to my AR.

This is perfect. My AR functioned fine with the stock buffer, but it was a very harsh weapon. Tried the H1 version and it helped, ordered the H2 and this one so I'd have a nice range... now if any of my friends want to step up in buffer weight I'll have a complete kit for them to try. Anyway, skipped up to this heavier buffer and my AR is a completely different rifle. So much smoother. Still no feed issues. Brilliant. Can't wait for my next range day.
