Newly designed and low-profile sacrificial lens assembly made of 6061T6 aluminum. It utilizes a 2mm thick sapphire glass window with AR coatings to prevent penetration of UTM and 6mm BB projectiles during force on force. The entire assembly is end user serviceable and weatherproofed to prevent the buildup of fog and condensation on the interior, which other sacrificial lenses lack. Aggressive cuts around the circumference aid in quick and easy installation and removal with and without the use of gloves. 

The sacrificial lens assembly is compatible with any and all standard PVS14 style objectives that utilizes the same internal thread.
