Here’s another one for the “new to me” category. Steiner Optics has an illumination product specific to the shotgun platform. While researching weapon lights for a fun project, I stumbled across the MK7 Battlelight, a magazine tube endcap replacement that provides 350 lumens of forward throw light. The complete unit only adds four inches of overall length,

My one main concern revolves around switch placement. The button is pretty far forward for a ‘momentary on’ type of use especially for my project which features a shorter barrel. However, I would like to install/use one myself before passing judgement one way or the other.

Street price hovers right around $180.

Steiner MK7 Shotgun Battlelight

The compact, ergonomic design of this 350-lumen mini-light makes it the perfect tactical shotgun light. A shotgun end cap attaches directly into the magazine tube and replaces the factory spring cap.

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.
