Looking at the Surefire x400 600 lumens light and green laser combo for my new DDM4V7slw ...so far I’ve tried to keep everything super lightweight and only put a t-2 and a lightweight sling and some magpul backup sights. Was thinking this x400 would be good weight wise but I’ve not seen much about how it goes mounted on a home defense carbine but mostly used on full sized handguns. Anyone used one of these with success?
