fps

[Sabre1]

HI, i have a stock g&g scar it shoots about 335-340 on average,

if i want to get the fps lets say 380- 385 what step should i take?

is it just the spring i should change, or are there other mods i must do?



thanks in advance

You could change to an m120 spring, which would bring it around 400.

Thanks , will that increace wear on the mechbox,or will it be ok?

A M120 is liable to go beyond 400fps.

You shouldn't need to change anything other than the spring. G&G mechboxes come with everything you'd need to support up to a 400fps spring. Wear will increase with a stronger spring, but it should be fine because the increase is only moderate.

Try a Modify SP100 spring, SP110 at the most. The SP100 brought my GR16A3 from 360fps to ~395fps. I think the SCAR barrel is shorter than 509mm, so you should get less than my numbers.
