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.

Great product

by Truckdad24, Verified Owner from GA, United States Written on March 2, 2025
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… �

Good for the price

by Michael, Verified Owner from PA, United States Written on March 24, 2022
Overall the product works as a carbine buffer. My one complaint is that is always important to a RECCE rifle, and not significant; but, the the buffer was 0.85g overweight. I would recommend the buffer for non-mission specific setups; but, be cautions if you are nickel and diming your weight.
Pros:
  • good price
Cons:
  • out of spec
Best Used for:
  • general use
Would recommend: Yes

Hard to go wrong

by petok, Verified Owner from GA, United States Written on February 9, 2022
This buffer is solid, well constructed, and comes at a good price. The weight is propper and it functions as expected. Used this to slow the action down a bit when running suppressed. Happy with the results.
Pros:
  • Price
  • Construction
Cons:
  • None
