Ok I hear people on here refer to different rifles like MK12 mod 0 or mod1 or MK18 and there are others people list, some I know .
But I was wondering if there was a list of what these rifles are just so I have a better understanding, same with ammo too, XM193 and 855 I know, but there are several I don't. Is there some sort of list for that too.
Thanks for pointing me in the right direction
