I plan on putting a Magpul UBR stock on it and it says in the manual to only use a carbine buffer & spring I believe, does anyone know why they say this? I was thinking about going to a heavier buffer to slow my bolt down a bit, should I not do this with the UBR stock?
Another problem I've been having is that my feed ramps gouge the crap out of my bullet jackets. If i chamber the same round twice I just throw it aside to be pulled because the jacket is so badly gouged. Has anyone heard of this before, is their an easy fix, like fileing an edge or do I need to buy & install a new feed ramp?
