    Reduced the recoil and made smoother operation of a Saint Victor 9mm.

    KAK AR15 9mm Carbine extended buffer 8.4 oz

    This dead blow style buffer works great with my AR9 build. I was using a standard heavy buffer at first but when I decided to put a binary trigger in it didn’t want to run properly when running fast. This buffer cleared those issues right up. I’ve done 2 AR9 builds with this buffer and they run perfectly.

    I put this in my H&R DOE and it’s money! Definitely an upgrade from the stock 3” buffer that came w/ it. Blow back 9, I believe is the name, led me here! Very glad I stumbled across his YouTube channel for all things 9mm PCC!

    This with a standard carbine spring in an Aero Carbine Enhanced tube is the solution to the ARC FireFRT Totally reliable in semi and frt. Nicely made dead-blow buffer with sliding weights. Eliminates bolt bounce. If pcc ar is your thing, keep a couple of these on the bench. KAK shipped reasonably fast

    8.4 OZ EXTENDED BUFFER

    Posted by DAVID HARTLEY on May 1, 2025

    I built a 9mm AR and was having a couple of minor issues, it didnt feel very smooth and feeding a couple of times. I changed out the buffer I had in it for the KAK extended 8.4 oz buffer and its been great. its cycling much smoother, no feeding issues. I wish I would have started out with this. Definitely recommend it.

    AR9 Buffer

    Posted by Chris Johnson on March 20, 2025

    I upgraded to the KAK 8.4oz buffer on my AR9 after reading some reviews from Blowback9. This combined with the KAK flat wire buffer spring made a big difference in the overall feel. A++
