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

by -

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

by -

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

by -

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.

It'll buff out.

Truthfully, bought this for the three tungsten weights for an intermediate buffer. The weights came in at 43.12g, 43.25g, and 43.26g. I don't see any reason why the body and green buffer pad wouldn't preform just as well as a higher priced buffer. I guess you wouldn't be able to brag to all you AFRCOM pretend friends that you spent 45 buck on a "********, ****, or ***" buffer. And Primary Arms always ships/delivers fast with great prices. TEXAS!

AR-15 build 762x39 and a 20 inch barrel; rifle length gas tube.

by -

Why? - because I can.

The short of it is, this H3 Buffer resolved my fail to eject in my current build.
Barrel: 7.62x39 20 Inch w/rifle length gas tube.
Gas block: size/unknown, came with barrel
BCG: Bear Creek Arsenal for the 7.62x39
(I had this as an extra BCG from a few builds/years ago)
Stock: MAGPUL/Carbine. Replaced with a rifle stock and related spring.

Previously using the stock rifle buffer; it did pull the round from the barrel, but failed to eject and load the next round.

Ejecting rounds solidly at 3 O'clock now.

Nice Part. Thank you

by -

Seems to be a quality part, I took mine out of the box and threw it on the precision crankshaft balancing scale, and it came in at 5.715 OZ. Much quieter in your hand when you shake it compared to the palmetto black std carbine buffer , and the gold andersons. Seems that the tungstens inside have less clearance, but plenty to buffer. Best deal on the internet!

Perfect cure for over gassed heavy hitters

by

The original buffer weighed in at 2.92 oz, fine for 5.56 and similar. The brass from my .458 SOCOM was landing 6-8 feet to my right and 8-10 feet forward. The EXPO ARMS H3 I received weighed in at 5.54 oz. Brass falls on the bench 2-3 feet to the right and slightly forward. More importantly, the rifle STILL runs flawlessly! Don't think it's my imagination that there is more felt recoil, seems to make sense that it would. Anyway, the buffer has this thumper running right, couldn't recommend highly enough!

Full auto

I have this buffer on a full auto system. It runs flawlessly every time. Haven’t had a F2F or a pause in firing since I got it. it holds it’s on for sure
