KAK Industry AR15 9MM Carbine Buffer Extended, Heavy 10 oz

Thanks to the wealth of information that is blowback9's wordpress I became aware of the sliding weight dead blow buffers and wanted to replace my stock solid steel buffer with one of these. I bought 2, one for each of my blowback operated AR9s. One weighted 10.94oz and the other 10.84. This increased my total reciprocating mass (bcg plus buffer weight) to between 24-25oz and made a noticeable improvement on recoil. I shoot my PCC competitively and this made a difference on follow-up shot speed as well as reducing the recoil while also increasing reliability and negating any possibility of bolt bounce. 10/10 product, well worth the coin.

I swapped the 5.5 oz buffer for this 19 oz buffer and the gun runs smoother no risk of out of battery detonation. As always great products from KAK

This buffer took away the issues I was having with my AR9. It runs flawless now.

Works perfectly,no bolt bounce . Cycles will all the ammo I put through it,suppressd and unsuppressed. Combined with their flat wire spring ,it is absolutely perfect.if your doing a blowback ar9 you can't go wrong.

This is a well made buffer, works great and at a great price. I'm very pleased!

My colt RO639 came with a 3.75 inch 5.4 ounce buffer. With 9 mm NATO, it flung brass to the other side of the range. Ejection was violent. With the addition of the 10 ounce heavy buffer, my brass winds up in a neat little pile 8 feet to the front right of me. Absolutely the best thing for my gun.

the 10 ounce worked really well in my jagger aut tactical ar pistol, along with a kaw valley .308 spring, perfect combo

It's the buffer you need in a 9mm blowback ar if you want it to run reliably

Weighed mine when it arrived and it is 9.8 oz on my scale, which is good, because on a 9mm blowback heavy is good. Shoots flawlessly and smoothly.
