Steiner Optics' versatile and powerful Mk7 Battle Light LED Weaponlight is the ideal compact illumination companion for your firearm. While the light fits comfortably in the hand, it comes with a Picatinny/Weaver rail mount and an end cap for Remington 870/1100/1187 shotguns. The cap attaches directly into the magazine tube and replaces the factory spring cap. Sporting two outputs from a low utilitarian 10 to a high 350 lumens, its Total Internal Reflection (TIR) lens is factory-focused to produce a smooth 10° beam without holes or hot spots that has been optimized for maximum throw.

To cut weight and reduce user fatigue the light is made of a lightweight aluminum alloy and weighs in at just 4.1 oz. Designed for durability, the housing features a corrosion and scratch-resistant anodized finish, is O-ring sealed to make it waterproof and submersible to 9.8', and its broad operating temperature enables its use in most weather and conditions.

    Also available for Mossberg 500 and Baretta models

    A very high-quality item. These fit the Remington models as stated, but if you want to put one on a Mossberg 500, you'll need a different adapter. Look for Steiner #9171. For certain Beretta models, look for #9172 or #9173. Adapters for those are about $35. Note that these lights will NOT fit a Mossberg 500 with a breacher barrel. Doing it this way beats paying full MSRP for part numbers attached to those other shotguns.
