Ok, another question, i've read thru the whole thread, well nearly....and I have a few questions about internal upgrades..
WGC do a magic box cylinder, magic box piston, laylax aero cylinder head, laylax piston head, laylax spring guide, and a prommy air nozzle. Will these parts all work together seemlessly as they are different brands.. Oh I already have an eagle6 M100 spring which I wanna use. The aim is to get to 350fps max for my UK site limit...
