EOTech debuted its newest holographic weapons sight accessory at this year's SHOT Show range day, showing off the drop-in Laser Battery Cap for its 512 and 552 optics.

The system simply replaces the current AA battery pack with a new one that sports both an infrared and red visible laser that are activated by toggle switches on the side. The pack also has embedded inserts for pressure switch activators.

The LBC is waterproof to 10 feet and lasts on two AA batteries for up to 60 hours of continuous use. With a suggested retail price of $285, the LBC for the 512 and 552 holo sights is an affordable upgrade to your existing battle tested optic.
