Product Info for GBRS Group Lerna Red Dot Sight Mount

Lerna is the first stand-alone optic mount designed for end-users that offers a 2.91'' Optic Centerline for faster target ID, regardless of gear/equipment obstructions, ie. EarPro/Comms headsets, Gas masks/CBRN, and Night vision use. A higher Optic allows for a more athletic posture and ''Heads up'' attitude that enables the end-users to maintain a vertical spine which translates to body armor or ''presenting plates'' to the threat. This ''Heads up'' style allows for faster processing speed and increased situational awareness.image
