I was looking for the H3 buffers, and these were just what I was looking for. Correct weight, nicely made. Also, OP contacted me regarding a possible delay, but they showed up very quickly.

Go with a dead blow!

by Para-Shooter, Verified Owner from OR, United States Written on April 29, 2026
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 combination depends on the desired weight. H3's are usually all tungsten hence the price. In this case brass is used, and at 5.4oz should tame any bounce issues. If rate of fire is your thing, buy an adjustable weight kit, start at 4.7oz and gradually add weight until reliable cycling is reached. The added bonus of reduced recoil and not beating your firearm to death. Is this "the best" buffer available? No. Is it the best H3 buffer under $40 (on sale), most definitely!

Do not use with Atrius Super Selector

by Bill, Verified Owner from TN, United States Written on April 26, 2026
I bought two of these to go into AR-15s for the recommended H3 buffer. Nothing but light primer strikes on both weapons. Changed out the buffers and they ran like a champ.
Pros:
  • Low Price and available
Cons:
  • Will not work with Atrius
Best Used for:
  • Semi-Auto
Would recommend: No
