EOTech, the Ann Arbor, Michigan-based division of L-3 Communications Warrior Systems, has unveiled their Model 512 Laser Battery Cap. Click here to watch a video for more information about this new product from EOTech.

This drop-in replacement laser battery cap replaces the old cap on all Model 512 holographic weapon sights. It is compatible with a Weaver mount or a MIL-STD-1913 rail. In addition, it runs on two 1.5 V AA batteries. The Model 512 LBC is perfect for home defense and training, as it has an integrated red visible and IR laser which enables the end user to improve their skills in both target acquisition times and aiming.

“The 512 and 552 Holographic Weapon Sights have been some of our most successful products,” said John Bailey, Director of Product Development. “This new Laser Battery Cap (LBC) doubles the aiming capability of the HWS without incurring the added cost of an entirely new sight.”

The manufacturer suggested retail price for the Model 512 Laser Battery Cap by EOTech starts at $285. The entire sighting system can be purchased for $729.00. See below for additional details.
