GBRS GROUP LERNA OPTIC MOUNT KIT FOR AIMPOINTA(R) ACRO 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. SPECIFICATIONS Materials: Mou Mfg: Gbrs Group
