AIR BRAKE piston head bearing in POM with double O (TPAA).
The most silent among those produced by the FPS for shotguns with up to 24 shots per second.
Its adoption creates an air cushion that softens the blow between the piston head and the cylinder head ensuring maximum silence.
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 TPAA head can also be used without shims, like a normal piston head.
