The Speed Airsoft Bearing Piston Head (SA3036) is one of the most advanced piston head designs in airsoft. The piston head is CNC machined aluminum, and is Made in Canada. These use a U-shaped cup o-ring instead of a standard o-ring, which delivers perfect compression every time and releases fully on the draw stroke for optimal performance.
The bearing piston head relieves twist on the spring for smoother gearbox cycling.
