AIR BRAKE PISTON HEAD BEARING FPS (TPAABK)

AIR BRAKE piston head bearing in POM with double or (TPAA).
The most silent among those produced by the FPS for shotguns with bursts 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 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.
Adjustment levels are 1-2-3- or 4mm if all shims are used.
The TPAA head can also be used without shims, like a normal piston head.
