Piston head bearing in POM with double o-ring and piston engagement angle adjustment (TPPA).
One of the lightest among those produced by the FPS for shotguns with bursts up to 25/30 shots per second.
Its adoption lightens the weight of the striking mass composed of piston and piston head with a significant reduction in mechanical stress and noise.
Using the shims supplied, it is possible to find the right length of the train formed by piston and piston head, to obtain the best possible engagement angle with the teeth of the sector.
