EOTech CFL-053-4 LG Long Gun Remote Switch with Straight Cord for M3X & M6X Tactical Illuminato

I love it. And it works great with the laser battery cap replacement for the 512 and 552 red dot sights. The sticky tab on the back of the pressure switch is not that great but that is easily remedied with a good spray on adhesive. In my opinion if you buy the laser cap definitely get this as well.

Great addition to the 512/552 Eotech holosight setup. Be aware of the relatively short length of the cable so placement needs to be perfect. I put mine along the right side of the handguard of my AR. The velcro stickyback is not the strongest but holds as long as you don't tear the switchpad of the velcro without holding it down, ie, the velcro is stronger than the stickyback. I consider this standard and not a detraction from the product. It may hold stronger on a traditional AR grip rather than an aluminum hollowed out grip with a gas piston system.
