i want to buy an ar-15 and i think i've made my decision on what to buy...almost.
i'm looking at cmmg and am trying to understand the difference in their models that say socom a1 versus the ones that don't. F-1454H A1 is a socom model for example. Has something to do with a grenade launcher (which is something i don't really want). Is it visible on the gun?
On many ar's (with m4 handgaurds) i see an area on the barrel about two inches in front of the front sight where the barrel is skinnier. Is this the grenade launcher flats they're talking about?
second question is this...what is the benefit of going with a phantom versus an a2 flash hider?
