So about 3 week so ago I was on fire for an M4a1 14.5 pinned and welded ar15. I was looking at the colt and the fn. for some reason I just felt like I wanted the fn more. Now the colts have all but evaporated and I and crying myself to sleep at night. I've read here and there that the fns have better barrels and are held to better standards. Can anyone confirm this? What do you guys think?
