Surefire km2-c head is a very robust economic solution if you have a surefire m600 ultra scout light - SureFire M600 Scout Light IR/LED Upgrade Bezel Assembly

After purchasing night vision, I needed to have an ir laser/ir illuminator for my ar15. I initially purchased the surefire m600 ultra, but didn't had enough in my budget for an all in one vis laser/vis illuminator and ir laser/ir illuminator device. I wanted a robust Vis/IR laser unit so I purchased the holosun le221. The holosun le221 doesn't have an ir illuminator, but I did have a surefire m600 light. I purchased this head because it allows me to utilize a bright flashlight and also served as an IR illuminator. Now the only obstacle remaining was a solution that would allow me to utilize the ir laser/ir illuminator at the same time and the ir illuminator separately. The Unity Tactical TAP SYNC Switch was the perfect solution for this. I can utilize the IR laser/IR illuminator together and separate and if I just want the laser, I can press the botton on the top of the unit. If I want to use the flashlight, I just habe to turn it a couple notch. There are three settings you get when you install this head. One turn with an audible click you get the Flashlight, the next turn, a convinient off setting in the middle, and the final turn, an IR illuminator. This product is a very affordable solution that allows you to utilize existing equipment if you already have the m600 light, but want to purchase an slightly less expensive aiming laser module while retaining the utility of a second flashlight.
