How to lower FPS in Gas Guns (SMG-8)?
 

Hey there,

So I want to use the SMG-8 in a CQB field near me, but the FPS limit at the field is 350 fps.
The SMG-8 I want to use is 360-400 fps.
How can I lower the fps? Can a simple Element M95 ST spring do the trick?
Or will I have to use the dust cleaner as gas?

NPAS.

You can lower or increase FPS with an RA-Tech NPAS.
