I want to put a Surefire M300A on my AR. I do not have any rails on the forearm. I don't want to use a VFG. I want to leave the light off most of the time, but be able to attach it quickly. I'll just use the tailswitch... not a tape switch. Would I be better off to use one of the railed sections that attaches to my forearm, one of the railed sections that bolts through the front sight base, or one of the railed sections that bolts onto the bayonet lug? Or, am I missing an option? Thanks, Jerry.
