Hi,

I have a G&G M14 Veterans, just try it out yesterday, it running 430 fps with 0.2 BBs. I think it using a M130 Spring. I would like to have it run at 400 fps (outside game). 2 questions:

1) Can I use standard spring (like for v2 & v3 mechbox)?

3) What spring should I consider for 430 to 400 fps?

Thanks,

Bong
