Re: weapon mounted light
I am not a fan of extra weight or bulk, so my preferences tend to reflect that. I really like the Surefire Mini Scout, and I replace the mount with a Larue offset. Recently I acquired one of the new Surefire x300 Ultra's, and it is much brighter (500 lumens vs 110,) and it weighs a hair less.
I do a fair bit of shooting at night but not much past 40 yards or so. I have yet to shoot the Ultra, but I have compared it to the Scout and it is noticible. That said, in the shooting I have done, 110 lumens was more than enough to get the job done.
