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. Recommended Torque: 45 In./Lbs. *NOTE: It is recommended to use Fix It Sticks' Small Torque Limiter (SOLD SEPARATELY) to prevent over-torquing.
