Selling a Surefire MR07 Rail and DG-17 switch combo. The DG switch will only work with the MR07 rail adapter and x200/300/400. Picture down below is of my TRP (non railed) with the MR07/DG-17 and x300. I bought both a month ago but decided to go with a different set up. Both are in like new condition.
