Hi all. I'm trying something that many would advise against, but I want to use a rifle buffer tube on a 9mm PCC because I want the extra length of pull without adding pads on the butt stock. Is all that is needed a buffer tube spacer, and then I can use the carbine sized PCC buffer and spring, or is there actual math involved with calculating lengths and weights? For once in my life, I'm trying to sort it out before buying the wrong parts.
