Piston head bearing in POM with double o-ring and adjustment of piston coupling angle (TPPA).
One of the lightest among those produced by the FPS for rifles with bursts of up to 25/30 shots per second.
Its adoption lightens the weight of the impact mass made up of piston and piston head with a noticeable decrease in mechanical stress and noise.
Using the thicknesses supplied, it is possible to find the right length of the train formed by piston and piston head, to obtain the best possible angle of engagement with the sector teeth.
The adjustment levels are 1-2-3- or 4 millimeters if all thicknesses are used.
The TPPA head can also be used without shims, like a normal piston head.
