Brownells USA KNS Veper large caliber 13/09/2018

I have a Veper .308, that was over gassed, had excessive recoil and trigger slap. Installed the KNS unit, adjusted the length as needed at the range for proper ejection. Now all is good, recoil much less and no trigger slap.

Definitely recommended

Brownells USA Awesome!!!!!! 21/05/2018

A couple years ago I had my M92 barrel threaded 1/2x28 and put my AAC 7.62 SDN6 on it. The gun was way to over gassed. I was pretty disappointed. When I saw KNS made an adjustable piston,I was super excited. I installed the unit and adjusted my piston down 40 clicks. It runs like a champ now. This part is amazing?



To Brownell's - please carry these pistons for all the AK and Galil Ace variants. Currently you only carry and handful of what KNS produces. I see myself buying more.
