My first AR15 and I'm just getting into differences in things like rails. The rails on my AR15 does not have screws to remove. CMMG has on their website a rail that is taken down with a tool, after upper is separated from lower. Can't get to barrel until I know how to take down rail. Anyone there to help?
:confused:
