GBRS Group Lerna Mount Kit 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.

This is because anodizing is a complex process and there are factors that can affect the color, such as the batch of parts being produced and the material composition. However, these minor differences do not affect the quality or performance of the product. In fact, they add to the unique character of each FDE anodized part. We appreciate your understanding and we are confident that you will love the customized product you receive.
