Description
Finally, a drop-in solution for taming the notoriously-overgassed AK platform. The patented 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 KNS Precision 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. Most (but not all) AK's are over-gassed. 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 KNS Precision Adjustable Gas Piston System installed.

Variations in the AK platform, the use of some aftermarket parts and a properly tuned and gassed firearm may not greatly enhance the performance and may impede function due to under-gassing or interference.

KNS Precision have redesigned and improved the adjustment collar for your AK Adjustable Gas Piston. With robust collar geometry and the addition of a roller detent, this version is MUCH stronger and protects all critical components from impact.

There is no need to remove or replace your gas block for adjustability. Just change the piston and go shoot.

Small Bore/Caliber pistons are for .223", 5.56mm, and 5.45mm. They work better in AK's of ALL CALIBERS with less excess gas.

Large Bore/Caliber pistons are for 7.62x39, .308", and 7.62x54r.

**When selecting your piston please refer to the chart to ensure maximized compatibility with your firearm.**

***A small percentage of Commercial Spec firearms have the piston welded to the carrier, instead of the usual Rivet holding in the Piston. KNS Precision recommend purchasing a new carrier for the easiest installation.***

**** Vepr and Saiga Pistons will require drilling through the op-rod after screwing the piston into the carrier, due to variations in the staking location. These Op-Rods are Phosphated instead of Nitrided to allow easy drilling.****
