After doing some research I decided to on a KNS gas piston for my Galil 386. Most AK rifles are over gassed by necessity but this piston allows the user to adjust for a variety of ammunition. Optics Planet’s sale event saved me $40. I plan to upgrade...

In the beginning I do 10 click increments to figure out where the piston needs to be to be barely ejecting cases then I dial up 5 more to make it slightly overgassed for reliability sake.
When cleaning it’s easy to mess up so I usually write down my ...

The KNS piston is an excellent product I recommend for every AK variant owner. The install was easy with a hand drill, punch and hammer. My Chinese Mac 90 variant was so overgassed with a suppressor it was malfunctioning. It was very simple to tune i...

Really tamed my obscenely overgassed wbp jack 7.62sc. Shoots a little harder than my 5.56 MCX now. Crazy!
I dont shoot suppressed, just didnt need my ak bouncing around so hard. I am a firm supporter of this piston now.

I have the 13" 7.62x39. stock, this was flinging rounds 20 ft and i wanted to suppress. Ordered the AGPA8 and with port fully open, even suppressed, 10 ft and WAY smoother operation. Game changer!

All the way off for low power steel ammo. 15 clicks for hotter brass. Waiting on adapter to try supressed. Makes it even softer shooting than before.

Product Info for KNS Precision Adjustable Gas Piston System
Finally, a drop-in solution for taming the notoriously-overgassed AK platform. The patent-pending KNS Precision Adjustable Gas Piston System is a replacement for the AKs piston head that attaches to the bolt carrier in about 10 minutes with no major gunsmithing or permanent modification required. KNS Precision designed these Rifle Parts to grant the user 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 more than 15 feet. This can, but not always 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 over-gassed gun shoots with our Adjustable Gas Piston System installed.
There are many variants within this family of weapons and the only way to truly make certain you are getting the right system is by precisely measuring your existing piston and comparing them to the chart.
There is no need to remove or replace your gas block for adjustability. Just change the piston, and go shoot.
