EOTech Laser Battery Cap
EOTech has designed a new drop-in replacement Laser Battery Cap (LBC) that can be used on all 512/552 Holographic Weapon Sights.
The EOTech LBC combines the lightning-fast target acquisition of the Holographic Weapon Sight with the versatility of integrated aiming lasers to create an optic capable of excelling in any environment. These battery caps offer a low-power red visible and IR laser, making them ideal for home defense, CQB and force-on-force training.
The LBC’s operate through the use of an easy on/off toggle switch and come with an accessory port for a remote pressure switch (sold separately). They run on easy-to-find lithium AA batteries for between 36 and 60 hours depending on the laser type and usage. They are also waterproof to 10ft for up to one hour.
