Expo Arms H1 AR-15 Carbine Buffer with Blue Bumper

Works perfectly. Slight improvement over the 3 oz. stock buffer. The only issue I have, and I won't bother pulling a star because the price was so good, is that this came in at 3.6 oz. instead of 4.
<br>
<br>I'll go ahead and order the 4.6 and the 5.3 and see if they'll smooth it even further and still manage to feed properly.

That did it !
<br>My awesome AR build just took a big forward.
<br>And the Expo Arms Spring I ordered with this new buffer was really nice too.
<br>Smoothed out the recoil and made it shoot like a dream.

This will be my third Expo Arms H1. Only one has had the smallest rattle from loose weights inside. Coating has some room for improvement. However, it is only a buffer, if you send enough down the pipe like any rifle should put some wear on even the most durable coated buffers. Pinned well, zero change of slipping. So functionality gets this 5 out of 5 stars from me for the small price tag.

<br>From Primary Arms I can't as for much more. I placed my order Friday evening. On Monday my fairly large order arrived by USPS!

Works exactly as it's supposed to, smoothed out a PSA carbine rifle just fine. Finish was nice, and the color coded bumper is a nice touch for easily keeping different weights straight. I've used a few other Expo buffers and the bright colors make it easy to grab the right one out of the parts bin, or to pop it out and check your weight when you run multiple uppers on the same lower . A small but useful feature.

This 4 oz buffer relaxes the stock KAK carbine buffer. I’m running a 10.3” .070 gas port stock buffer spring and it was smooth and locked back in last round. The best value in the industry and the paper targets in the PA Packages are a nice touch! Shipping is always on point with PA! 5 starts for product and 5 stars for PA

Smoothed out an over-gassed carbine length AR-15 without any compromise in reliability. Great value compared to other buffers of the same type that sell for double the amount.

Just as good as a more expensive buffer, made in the USA and lifetime warranty. Can't ask for anything else.

Works perfectly fine compared to other high dollar brands.

Used to replace my 3 oz. buffer in my Windham Weaponry 16 inch carbine. Works very well and PA shipping was incredibly fast, 2 day to my door. Great job PA i will be a return customer for sure
