Mk3 Battle Light is rated 3.0 out of 5 by 4.
Rated 1 out of 5 by from Pressure pad fails when it gets wet. Our SWAT team has been using the MK 3 since Jan 2017. 1) Most if not all of them have failed when the pressure pads get wet. By wet I mean light rain, we are not submerging them. The lights will stay on or come onwhen not needed when the faulty pad is attached. 2)The pressure pad comes unplugged form the light very easily. 3) The switch is too small to flip around with gloved hands and you're nevfer really sure what setting it is on untill to activate the light.

Rated 5 out of 5 by from Exceptional compact lighting system I purchased this to compliment my custom 300Blk SBR. Due to the extremely small size of the rifle I needed a compact light, but did not want to sacrifice functionality or durability, the Mk3 met and exceeded the requirements.

Rated 1 out of 5 by from MK3 Love it, exactly what I needed for vis light and IR . Need a cap to cover lens like DBAL D2.

other LED IR lights I have tested emit a red signature easily seen at a distance at night. Does this light display that signature?

Asked by: Sgt 10
The Mk3 is the only eOptic that emits the red IR signature, all other IR illuminators do not

the Steiner Mk3 Battle Light . is it fit beretta px4 storm pistol

Asked by: taleb
Unfortunately the Mk3 battle light will not mount on the PX4 storm, due to only having one slot for mounting. I would recommend taking a look at the the LAS/TAC light.
