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.
