My reasoning for wanting to go with a mount like this is multi-fold.
1. I'd like to keep the light system quick-detachable as in being able to use a throw-lever mount or ring.
2. I'd like to keep the M4 forend clean and totally available for my hand to move around on; back or forward.
3. I'd like to keep the light as close as possible to the weapon to cut down on possible snagging.
4. I don't want a pig tail switch for total reliability and snag-free operation. I'd like a momentary switch with the ability to lock the light in the "on" position.
5. I'd like keep it off the barrel to prevent any change in bulet impact. Knocks the 659/660 series out of contention I believe.
I think my best option to fill my desires are:
1. Some kind of quick detach 1" scope ring such as the Leopold QRW or ARMS #22 ring (30 mm right?). I just want to make sure that what ever ring I use, the "throw lever" will lay flush with the weapon to cut down on and prevent snagging. If I went w/ the #22 ring I'd probably have trouble with a 1" diamter SF light.
I suppose the basic SF 6P with a shock proof bezel installed would suffice. I'd turn the light on via the back of my hand or a knuckle.
What is the part # for the shock proom bezel? Any other thing I need to add to the light to recoil proof it?
