Highly recommended - EOTech Drop In Replacement Laser Battery Cap for 512/552/518/558 Holographic Weapon Sights

I purchased the Laser Battery Cap with the RED and IR for my 558 unit for use with a Armasight Spark G CORE IIT Night Vision Goggle. The EOTech 558 works with Gen 1 - 3 night vision devices. This system works perfectly but both lasers need to be zeroed in separately. I would like to see rubber caps for the pressure plate plug-in points. Battery life is not as long as other sites, but AA batteries are inexpensive comparatively speaking. Highly recommended.
