ok so for the past year off/on i have been rebuilding a 2nd hand G&G l85, and now being at the stage of almost ready to skirmish, i am have having an odd spring issue.
little history, when i bought the gun it wasnt work, this i fixed with a new trigger and a small rewire. then disliking the none original piston/spring configuration, i swapped it for a new G&G L85 piston head, new spacer and new piston (please note the spacer is used as this has an original PSG-1 style top end, but the lower has been modified to v2/3 sector gear).
now on to me being abit thick, when i finally had all this done/cleaned/ready etc , rather than use a standard spring, i fitted a psg120 spring ... and got 370fps on 0.25's
so i ordered and fitted a psg100 spring ....363fps on 0.25's
at this point i realized that i should have used a standard spring , and i found a bag with what i believe to be a sp100 spring in it .... 368fps on 0.25's
other than going out and ordering another spring and trying that, anyone have any idea's on what spring i should fitt (to be below 350, on 0.2's)
normally i would say a sp100, but atm i am totally unsure
