Recently I assembled a couple of Scout style weapon lights using Arisaka Defense parts and wanted to throw together a quick article showing you guys the parts I used and some of the different options you have when doing the same thing. So I took my lights apart and started taking pictures from the beginning which you can see below.


As you may already know, Arisaka Defense started out making light mounts and rail accessories. Recently they have introduced their own line of Light Components that allow you to build your own Scout style light. They now offer both a 300 Series Scout Body (powered by a single CR123 battery), a 600 Series Scout Body (powered by two CR123 batteries) and their own Click Tail Caps. They also make an Offset Scout Mount (shown) for MLOK, KeyMod and CMR rails and an Inline Scout Mount for MLOK and KeyMod.

Many AR owners who have purchased a Scout light before have an extra factory tail cap or two laying around (Click Cap or Tape Switch) which will work great with the Arisaka bodies. For those users, once you choose your desired mount and Scout body, the only thing left to do is pick up some CR123 batteries and a new E1 or E2 head from Malkoff Devices.

If you don’t have any tail caps to start with, Arisaka Defense actually sells complete Scout lights with the Malkoff Devices heads. When I started piecing together my Scout lights, Arisaka didn’t offer Tail Caps or complete units so a buddy of mine gave me some tail caps and I purchased the Malkoff Devices E1 and E2 heads on my own. Since then I’ve picked up a couple of the Arisaka Defense Tail Caps. Shown below is the configuration that Arisaka Defense offers for the 300 Series Light and 600 Series Light. The biggest key is that you can basically get two lights for the price of one SureFire Scout light. The 300 Series complete light is $149 plus the cost of the mount and the 600 Series complete light is $159 plus the cost of the mount.

I personally like to use the the SureFire Tape Switch’s because it allows me to mount the lights on the right side of my weapon, giving me more rail space to place my support hand, etc. Currently I run the Arisaka Defense 300 Series Scout Light on my SBR with an SRO7 Tape Switch while I have the 600 Series Scout Light on a 16″ AR with basic tape switch held in place by a Tareinco Tape Switch Holder. I’m extremely happy with these lights. The heads are extremely bright with the E1 rated at 250 out the front lumens and the E2 measured at 325 out the front lumens.

I’ve put links to both Arisaka Defense and Malkoff Devices websites and social media sources below. Both have pretty active feeds to follow.
