I bought an SHS spring. I'd advise against it. horrible spring... The M140 was only a little stronger than my stock m120.

I need a bucking, and am not sure which. I'm getting a Prommy M150 and I was wondering what would be a good bucking to go with it.

I've got a Guarder sp spring. Haven't had any problems out of it, still strong after it settled and has a few thousand rounds through it. I'll probably stay with Guarder until something happens.
