I'm using the FFT 2 round extention with the original M4 spring. Works great!

No! Use the same spring.

Ok guys,

I've read both thoughts on using old spring(original) or new spring.

Where do i get a new replacement to go with the 2 round extension???

Thanx

carriercomp is the only place I know - it's a wolff spring apparently, but I don't think it's on their site
