Springs

[Guest Imanairsofter]

I need a spring that will give my gun an FPS of around 320, this means I can play at my local CQB centre. what should it be , M90 M100 ext??

Usually m90 springs will give ~295 fps and an m100 will give ~325 fps, so it depends on how much leeway your site gives over that limit. For example some sites list 328 as their limit but have a tolerance up to 350, any gun even .1 fps over can't be used.

 

Because of this I always choose m90 springs for my rifles as it's comfortably within most site limits even if I sacrifice that extra fps boost.

Be wary of quoting direct x spring = y FPS. I'm currently running an M95 in my M4 and it hits consistently at 345fps. Actual muzzle velocity depends greatly on how good your air seal is.

M90 means 90 M/S, so ~ 295 FPS.

An M100 = ~328 FPS.

 

As Lozart said though there can a big difference in actual velocity. You could alternatively cut down your existing spring to reduce power.

OK thanks guys!
