I have never used one myself, but I would venture that it would be beneficial, and I've talked to a few 4ID guys who have. Never heard anything bad about it. Leave it on when you're outdoors, and you're pretty much ready for anything, then if you have to clear a house, twist it off and go. My personal Preference is the Marine Corps style ACOG though, with the fiber optic and tritium. The Bindon Aiming concept is something I was able to wrap my head around, and the dedicated magnified weaponsight with BDC just does everything for me.
