Most Helpful Positive Review A Good Affordable 5.6oz Buffer That Works
I weighed the buffer. It’s advertised as a 5.6oz buffer but actually weighs 5.53oz. Not a big deal. After putting a few hundred rounds thru my AR9 build, I noticed the black finish on the end that contacts the BCG has started to show signs of wear, probably caused by the force from the Direct Blowba...

Most Helpful Negative Review sniper 9mm buffer
Low cost buffer, function was solid. Doesn’t appear to be super high quality by any means but still functioned properly. A decent low cost alternative and I liked the lighter weight i was looking for.

Solid & not aluminum

by CHT1, Verified Owner from FL, United States Written on December 19, 2025
The description says aluminum construction and 5.6 oz. (That would be with weights) but this is solid steel buffer, and since most AR9 are blowback with a solid bolt (AR-15 bolt & carrier moves) combined with the solid buffer it causes bolt bounce. Don't buy it, get a buffer with moving weights.
Pros:
  • None
Cons:
  • Will induce bolt bounce
Would recommend: No

Great Buffer

by Chris, Verified Owner from PA, United States Written on December 17, 2025
I didn’t have any issues with this buffer. It’s machined from a solid piece of metal and feels noticeably heavier than a standard AR‑15 buffer, exactly what you want when running a 9mm setup.

9mm buffer

by Ron Rigz, Verified Owner from CA, United States Written on November 1, 2024
Used on my 8" AR 9mm pistol build. Got a red carbine buffer spring combined with this buffer to slow down bolt cycle. Also reduced felt recoil a bit.
Pros:
  • EASY INSTALL
Cons:
  • None if used properly with good buffer spring
Best Used for:
  • Slowing cyclic rate on 9mm pistol
Would recommend: Yes

fixed my feeding problem with endo mags on 9 mm

by colthero, Verified Owner from WI, United States Written on May 22, 2024
I kept getting 9 mm rounds stuck nose up in the chamber. I figured my bolt was moving too quickly cuz I only had a standard weight. Bought this in order to weigh it down. Fixed my problem. I deduct one star because this is made of a solid piece of steel and does not have moving weights on the inside.

Bumper broke after 23 rounds

by law, Verified Owner from VA, United States Written on July 24, 2022
Waste of money. I fired 23 rounds of 9mm with this buffer and the end bumper shattered into pieces. I've never seen a buffer so that before. It's not worth returning. Just learn from my mistake and spend a few more dollars on a good buffer for your ar9

Heavy buffer

by Bigboy, from CA, United States Written on December 25, 2020
Excellent speed reduction for ar40 build. The additional weight noticeably reduces bolt carrier group action. A must add instead of the standard light AR buffer! Used a 5.3 ounce instead of 4+ oz to slow ejection and extraction.
Pros:
  • Perfect additional weight
Cons:
  • None
Best Used for:
  • Ar40
Would recommend: Yes
