KNS Adjustable Gas Piston Mod 2 Upgrade Collar

We've 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.

Our new collar design is backwards-compatible with the original non-mini version of our piston. Collar & roller have been Nickel Boron treated. Installation is a simple 5-minute process.

Kit includes:

-One Mod 2 Upgrade Collar

-Two Roller Detents

-One 2.5x12 Roll Pin

-One 2.5x14 Roll Pin

All current-production full-sized Adjustable AK Gas Pistons come equipped with this collar.

**Piston head & op rod not included**
