Finally, a drop-in solution for taming the notoriously-overgassed AK platform. The patent-pending KNS AK Adjustable Gas Piston is a replacement for the AK’s piston head that attaches to the bolt carrier in about 10 minutes with no major gunsmithing or permanent modification required. The user is granted an extremely wide range of gas adjustment for suppressed and unsuppressed use, as well as a variety of different kinds of ammunition.
A good rule of thumb to determine if our piston will be useful, is if your gun throws the brass over 15 feet. This can signify excess gas pushing the carrier back at a higher velocity and pressure, than is needed for effective operation. This causes more recoil, more wear and tear, and less controllability. Many users are surprised to feel the difference in how their gun shoots with our Adjustable Gas Piston System installed.
There is no need to remove or replace your gas block for adjustability. Just change the piston, and go shoot.
They work better in AK’s of ALL CALIBERS with less excess gas.
