Most Helpful Positive Review Go with a dead blow!
If your rate of fire is creating bolt bounce or even won't run, you MUST run a "dead blow" buffer. These are not the cheap one-piece steel buffers, those are junk, don't waste your time and money. Dead blows usually have three (or two) internal weights consisting of aluminum-steel-tungsten, the comb...

Most Helpful Negative Review NOT good for FRT. Not proper weights
While the overall weight of this may compare to an H3 buffer, it does not have three tungsten weights like a traditional H3 buffer. It does Not prevent bolt bounce like it should. Fast shooting will result in out of battery hammer drop. Tested with multiple uppers, multiple lowers, multiple springs,...

Didn’t need

by Cutterman, Verified Owner from GA, United States Written on October 3, 2026
Ordered this buffer because everyone and everything I read said that I had to have it for my frt to cycle but my dpms would not so I went back to the standard that was in it and it runs perfectly

KAW H3 Buffer FRT

by Blain Aldous, Verified Owner from ID, United States Written on October 2, 2026
Purchased two of these buffers for my frt builds. I read the reviews before purchasing and it seemed like everyone was having good luck with them. They will not run either of my frt AR 15s. The stainless steel body is very nice but instead of tungsten weights they used brass. I don’t think there is enough reciprocating mass to compensate for bolt bounce. I swapped out the buffers with an H2 I already had and both run great. Pretty disappointed I will need to source two more buffers to correct the issues.
Pros:
  • Nice finish
Cons:
  • Will not run my FRT
Best Used for:
  • Standard rifle recoil dampening
Would recommend: No

great buffer weight for the money

by Jeff Creller, Verified Owner from FL, United States Written on September 18, 2026
I ordered this for my AR pistol because I’m installing a frt. This weight is made the proper way with the 2 weights inside of the buffer. Most affordable buffer weights are solid one piece construction and don’t work well with frt. after doing some research, I found for the money, the Kaw Valley buffer was a good choice. I purchased the H2 and H3, just waiting for the opportunity to go to the range and try them out.
Pros:
  • value
Cons:
  • None especially at price point
Would recommend: Yes

Just buy an H-3

by Timbo74, Verified Owner from WI, United States Written on September 13, 2026
Do not buy this gimmick. Yes, it has reciprocating weights, and yes it is the weight of an h-3 buffer.
The main problem being the buffer body is heavier than the brass weights! A mil-spec h-1 buffer has significantly more dead blow effect, than this h-3 buffer, which means this buffer is a gimmick.
Best Used for:
  • paper weight
Would recommend: No

The additional weight does help with the AR15 locking open correctly instead of catching upon the magazine.
When shooting when feeding from the magazine it should it should help reduce jaming.

Price was right and the weight was spot on. It's a buffer, not that much to talk about.
