|Tipoff Blue filter the M3 Millennium Combatlight
The listed filter provides you with the ability to alter the light to a blue beam. It is excellent for reading maps, as it does not impair your night vision. The blue beam was originally designed for police and hunters to illuminate blood trails. The filter can be flipped open to provide white light when needed. Some of the new millennium model filters feature a Pyrex lens and all have our new positive locking closure to ensure the filter stays in place during tactical operations. FM13-17 fit the “A” Series, FM23-27 fit the “AB” and “B” Series.
