New design in terms of CUP piston head. It is made of durable rubber, so the impacts of the piston are more softer. The shape of the head ensures a large contact area with the cylinder wall and but smooth and easy bolt pull back. There is no metal-to-metal contact in the cylinder and there is less friction.. As the pressure increases during the shot, the rubber it will press even more against the cylinder and a perfect seal will occur without air leakage.

The piston fit in A&K or A.C.M spring action SVD rifles. . Please apply silicon oil or grease on the cylinder head or in the cilinder wall during assembly process.
