SureFire FM70 Filter Assembly for 1.125" or 1" Bezels - Red, Blue, Green, and Black Out Lenses Included. The flip lens feature gives the ability to quickly change from a colored lens to white light. The black out lens can be used to prevent accidental light discharge, but is easily snapped open when light is needed. The FM 70 kits comes with two rubber grommets that allow use on both 1.0" and 1.125" head lights. Military & Law Enforcement departments please call us for special price. By SureFire.
