"Put in my aug with a separate nozzle and bumped my FPS from 330 to 360.
by Alexander A. on 03/09/2020
"Fit and finish was good, the cylinder head that makes contact with the nozzle is not polished. And you will find that the nozzle feels like it is just .001" smaller than the cylinder head, several reviews state this even on the SHS website however everything does work if you follow these steps: Throw on some lubrication on those seals and it will move much more freely. If you have doubts throw it into the gearbox with the tappet plate and return spring installed and check it, nozzle snaps back fully forward with no delay.
