Most Helpful Positive Review Solid h3 buffer
I searched high and low and could not find a better buffer in H3 for a better price. Seems well made and functions well in the gun. Great thing about an H3 buffer is you can also get a cheap buffer which comes with pretty much every receiver extension and you can knock the retaining pins out and make what ever buffer you want, be it an H1 or H2 or H3.

Good quality

I have Odin adjustable buffers, to test and tune, but found their grub screw can eventually walk out, so I prefer a standard buffer long term. Scored this one at a great price. I might borrow a tungsten weight from it to create an H1 or H2, but either way the value was great.

Great product

My H1 wasn't strong enough and was having malfunction but the H3 alone was enough to solve the problem and didn't have to replace my spring

awesome upgrade

by AES Guns, Verified Owner from KY, United States Written on February 21, 2025
Since I have an 8” Blackout with an optic, the Leapers UTG H3 Hard Coat Recoil Buffer could be a solid upgrade for my setup, especially if you’re running it suppressed or dealing with an over-gassed system.

Why It Makes Sense for Your 8” Blackout
• Smoother Cycling & Less Bolt Bounce – With a short barrel, especially in .300 Blackout, you might experience a sharper recoil impulse. The H3 buffer helps slow the bolt down, making cycling smoother and reducing wear.
• Better Suppressed Performance – If you’re shooting suppressed, the extra weight can counteract the increased gas pressure, keeping your rifle from feeling too violent and improving reliability.
• More Controlled Recoil – While .300 Blackout isn’t as snappy as 5.56, an H3 buffer can still help keep the rifle stable for faster follow-up shots.

Things to Consider for Your Setup
• If your Blackout is already running well with an H2 buffer, switching to H3 might slow

Very Affordable Upgrade!

by Brandon G, Verified Owner from AL, United States Written on April 7, 2024
Very affordable upgrade. I’m using this for my AR-47 build to make it run softer since the gas in a pistol format is HIGHER…This should smooths out that recoil impulse and make it run smoooother… �
