I recently purchased a Cyma Vsr10. Was interested in the Stalker Piston for the quiet noise. Purchased this not realising I needed a 90 degree trigger box (as a review stated) I had no idea the ssg10 and vsr 10 have different options. But I have a new trigger box , Maple leaf CNC 90 degree zero to be exact , tried it, the trigger stopper is stiff but goes in with a knock. I go to perform a seal test and it’s still incredibly loud and is holding no air , this is from the nozzle aswell ! Idk ! Is there any advice on what can be done or if anybody has had a rare piston problem like this or air seal problem ? Much appreciated.
