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.
Users are granted an extremely wide range of gas adjustment for suppressed and unsuppressed use, as well as a variety of different kinds of ammunition.
Key benefits
- Updated Mod 2 collar
- Tool-free adjustment
- Reduces recoil
- Tune almost any AK for suppressed use
- Decrease cyclic rate for full-auto fire
- US-made 922r compliance part
- Piston head assembly made from corrosion-resistant stainless steel
- All surface parts nitrided for durable, low-friction, easily cleaned operation
- Patent Number 10,330,480
Fitment / selection notes
- If your gun throws brass over 15 feet, the piston may be useful.
- Small Bore/Caliber pistons are for .223", 5.56mm, and 5.45mm.
- Large Bore/Caliber pistons are for 7.62x39, .308", and 7.62x54r.
- Vepr and Saiga pistons will require drilling through the op-rod after screwing the piston into the carrier due to variations in staking location; these op-rods are phosphated instead of nitrided to allow easy drilling.
- A small percentage of Commercial Spec firearms have the piston welded to the carrier (instead of rivet holding). KNS Precision recommends purchasing a new carrier for the easiest installation.
