[_Whiskey_]

Ok so my gun on a element m90 spring was doing about 311 fps on .20 bbs with the stock vfc barrel and hop up. I was expecting something abit higher than that. Now if i bump the spring up to a m100 by vfc would that possibly put me over the 350 fps limit? I do have access to a friends chrono to confirm, just looking for input before taking the whole dang gun apart.

Also with a angry gun 407 inner barrel 6.03 and modfiy hop up with vfc rubber (all i had spare to use) my fps drops to about 260 with .20s any idea on this?

Cheers
