Action Army VSR 10 bearing spring guide - Got it off a guy I know who plays at the local. Agreed on 12 euro which is half the price he paid for it shipped from ehobby.
Also yesterday at school I threw my cylinder head on a lathe and made a taper for better air flow. Also removed the air brake on the piston to firther improve air flow quality sacrificing some quietness but it's hardly noticeable with the big chunker of a sorbo pad on the cylinder head. Regreased the cylinder internals, polished the exterior of the cylinder.
All of this,along with the new spring guide gives me a very nice 315 FPS +/- 3 . .30s hitting at 1.13J on average,but I'm, not certain as I don't really trust the chrono.
The gun can be operated with just my ring finger. Some very light plastic on metal grinding can be heard from the cylinder guide rings but cannot be 'felt' probably just from wear. Will try get a hold of some delrin pipe and make some new ones at school.
