Works great for AR-9 builds
I purchased this buffer after a lot of research into building/tuning a 9mm AR-platform pistol/carbine. Since they operate on direct blowback, it is important to adjust your total reciprocating mass to reduce felt recoil, ensure proper cycling, prevent undue wear on the system, and (most importantly) delay blowback long enough for pressure in the system to drop to safe levels. As such, I was specifically looking for an extended (~4 inch) buffer with internal sliding weights, and the KVP-10oz meets both criteria.
The specific buffer I received weighed in at 10.25 oz which, combined with my 14.4...

4" heavy buffer
There are 4 tungsten pucs inside which alone makes it a good deal, by swapping in steel pucs 1 by 1 you can adjust its weight down from 10.5 oz
Best Used for:
- 9mm carbine
Would recommend: Yes

KVP Stainless Heavy Buffer 10oz for AR9
This 10oz buffer works great in a short barrel AR9 pistol. It’s a bit longer than the normal buffer to help cycling blowback 9mm platform to not over extend towards the end of buffer tube. Works great with a super safety. Make sure to use a stronger firing pin spring on a FM9 or PCC BCG to prevent 2nd round dead trigger. The OEM spring is super weak and will get 2nd round dead trigger from a light strike. Stronger spring and heavy buffer (make sure it rattles to prevent bolt bounce) will correct SS failures.
Would recommend: Yes

9mm Blowback essential
My 9mm AR pistol needed to be timed better than the 8 oz buffer. The bolt I chose was a little lighter than a previous build so I went with this buffer. An excellent choice. Flawless 8" 9mm build AR. Recoil reduced and accuracy improved. I recommend this product for this purpose.
Pros:
- Timing Fix
Cons:
- None
Best Used for:
- 9mm ar
Would recommend: Yes
