Upgrade piston for Snow Wolf Kar 98 rifles. Unlike the original plastic, this one is made of strong and light aluminum, providing a higher durability. Designed for stronger springs, air flows under the seal through six air channels and improve sealing. The optimal diameter of the sealing o-ring ensures a very good seal and thus a high and stable performance.
The inner diameter of the piston is identical to the original piston. No modification needed.
