TM M4 with madbull M100 spring -FPS???

[airsoft_ben_1989]

ok so in an otherwise standard (minus metal bushings) TM M4 what kind of FPS should i expect?

i have been told upto (possibly) 370, but with a local site limit of 355 i obviously dont want 370.

Thanks

what 370 with a m100 spring i would say around 335-355

depends on other things as well

great, tbh 340 - 345 would be ideal as i want to put a tightbore in at some point which could push it up a little bit so id be happy with a bit of space before the limit
