Frequently Asked Questions

What is a KNS adjustable gas piston and why install one on an AK?

A KNS adjustable gas piston replaces your standard AK piston, featuring a bleed-off system. This allows you to tune gas pressure, reducing recoil, improving cycling reliability, and enhancing performance, especially when using a suppressor.

What tools are needed to install a KNS adjustable gas piston?

The installation requires basic gunsmithing tools: a center punch, hammer, and a power drill with appropriate bits for removing the original rivet and installing the new roll pin.

How does the KNS adjustable gas piston work?

It has a click-adjustable collar that acts as a gas bleed port. By turning the collar, you can vent excess gas, fine-tuning the rifle's operation for smoother function and less felt recoil.

What is the process for removing the old piston?

First, center-punch the original rivet on the bolt carrier. Then, drill off the rivet head and use a punch and hammer to remove the pin. The old piston can then be unscrewed.
