My original plan was to get the Surefire M500A and just replace my M4 handguards.  But I got a DPMS bull barrel with free floated round handguards.  So I changed my plan and got a 4 rail gas block to just attach my 6P until I started reading on here everyone having problems with the 6P and G2 falling out of the mount.  So now how else can I put a light on my rifle?

Seems I read on a post that someone was having trouble with the scope ring option also.  Something about having to put "ranger bands" around the light to keep it in place?

how about bicycle innertube?

Is your free-floated handguard solid or slotted?  Does it have to be Surefire, or would you consider a Streamlight M3?

I used a Streamlight M3 AR-15 mount (basically a very short "Weaver" rail fitted for the M3 & designed to mount through the holes in the standard handguards with a backplate) on one of my DPMS [u]slotted[/u] FFHGs by mounting it through the slots - works like a charm.  Even if your FFHG is solid, it would only require drilling two small holes & you wouldn't be limited by the slots as far as light position.  (Mine [through the slot] is at the 2 o'clock position - quick-detachable & very handy.)

I have at least a dozen weapons set up to use the M3s & five M3s that make the rounds among those weapons (I do use dedicated Surefires on mytwo primary shotguns, though).  Just another option to consider...

OK thanks, I didnt realize I could use the slots on the handguards.  I do have an M3 on my duty weapon but I really am not a big fan of it.  I like surefires better but the M3 is smaller and cheaper which is why I got it.  But Surefire has that new light coming out in Jan. that looks like the M3 maybe I can put that on my Caspian and the M3 on my AR.

 I have the DPMS bull barrel set up with the 4 rail block... but I had a surefire 6z kicking around.  Using a 1" ring on the rubber grommets locked it in tight, and most likely gives it some shock protection also.

jenec.... can you explain what the "rubber gromets" are.  and what 1 inch ring did you use.  Maybe a pic?  Thanks.

I have a good idea... how about I patent a scope ring with little rubber feet inside it!!!  OK so I dont know how to do that but maybe a company could combine the two concepts of a scope ring and rubber to hold a flashlight.  Just a thought.

PS... And I want stock in the company that takes my idea.
