Description
Most AKs are overgassed, and a suppressor makes it worse: harder recoil, more wear, and gas in your face. The KNS adjustable piston lets you set the gas for how you shoot.
We install the piston, tune it on your rifle, and mark the settings for running with and without a suppressor. It adjusts by hand — no tools — so you can switch in seconds.
Piston, installation and tuning included.
Return shipping: flat $50, added at checkout — or free if you choose local drop-off and pickup at our Calhoun shop.
