Sentinel Mirrors - #34455. The Sentinel Mirror kit includes two mirrors and all hardware needed to mount the mirrors in a fixed or fold-in configuration. The Mirrors consist of a polypro plastic base and a 2.75" convex mirror which provides a large field of vision. The mirror brackets have been designed specifically for the Sentinel Hand guards and follow the lines and shape of the guard for a clean look. They can be folded in when not in use or when using a tight fitting cover. The brackets attach directly to your Sentinel Hand guards with a few simple steps and will work with the Sentinel Armor - 34477, Hand Wrap Attachment - 34253, Hand guard Flare - 34276 and Hand guard Gauntlet - 34258. Note: Armor and Hand Wrap Attachment are not compatible with the fold-in configuration.
