Dont know if it is the original piston as the gun doesn't have the Maxigrip, and other parts had been switched on the gun too.
Its better now with a deburr and proper lubrication, but the full circumference piston would be best.
I had an Oldschool HW85 like that, Evert.

The cutout has to be there to clear the scope rail but nobody had ever smoothed the corners of the slot out so it marked the top of the cylinder.



All the best Mick
