TM P90 spring question.
1 August, 2011, 22:07
I'm asking this in the tech section because it looks like a tech question. How much FPS would I get out of a TM P90 with an M100 spring? I'm worried about it being above 350FPS for site legality and all that.

Re: TM P90 spring question.
330 on a SP90? So I guess a 100 would push FPS past 350. Thanks for the reply. I know what spring to get for me P90 now.

Re: TM P90 spring question.
Don't confuse the
SP
90 with a
M
90
A M100 spring should give you around 340fps... but a lot of spring makers seem to be getting "hotter" now. I put an Ultimate M100 in my weapon last weekend... pushing 380fps!
SP90 by Guarder is a good bet
