    Just Right

    Just what I needed to slow er down. AR10/.308 cycling way to fast, not anymore.

    AR-10 Heavy rifle buffer

    Posted by Mike on July 14, 2023

    The KAK heavy rifle buffer reduced felt recoil on my suppressed AR-10 308. Now I’m able to stay on target for faster follow up shots.

    not sure if it's necessary

    Posted by Top 'O Texas on April 13, 2023

    Bought this for a short mag build, but as heavy as it is it might not be necessary for it to be this heavy. Other than that I'll report back when finishing the build.

    Buffer for 9mm rifle build

    Posted by Meteor1 on December 5, 2022

    Great buffer for a 9mm blowback build. Extra length and weight is what was needed for the rifle to cycle properly

    458 SOCOM

    Posted by David on December 28, 2021

    I used this in my AR15 458 SOCOM with a Rifle Receiver Extension. I also used a David Tubbs Flat Spring. This Buffer really "Tamed the beast". Nice eject at 3 o'clock abourt 24" away.

    This buffer dampened the recoil by at least 20% in my .50 Beowulf rifle build, 11/10 would buy again. -L

    The way to go

    Posted by Ron on July 2, 2021

    Like other guys, taming and slowing down the action on an AR-LR-10, this 9.3 oz. heavy buffer along with a Tubbs flat wire spring solved the problem of the bolt slamming the reloads into the chamber too fast and hard, it was causing the bullets OAL (overall length) to lengthen by various thousandths. The heavy buffer feels so much smoother, not so snappy when fired. Also, I think I must only live about sixty miles from KAK, and got my buffer the next day after ordering!!

    Bought Buffer to tame over gas condition with my PSA AR10 .308. Very nice product, great fit and finish. Good price for the quality.

    KAK Upper .358 / .308

    Posted by john on July 2, 2020

    I have a DPMS AR-308 that consists of mainly KAK upper parts... Barrel, BCG etc. I would have saved money if I'd just bought a complete upper. I put in the Heavy Buffer along with an adjustable gas block after reading some of the reviews here. It made a very noticeable difference with both the .308 and .358 chambering. The recoil is very tolerable and SIGNIFICANTLY less than firing the .308 or .358 in a bolt action. I haven't tried yet, but I could probably fire 100 rounds through my .308, in one afternoon, with no bad after effects. If I had it to do again, I'd buy the individual tungsten weights and just do it that way.
