GBRS GROUP LERNA MOUNT KIT MRO BLK

Description

The GBRS Group Lerna Mount Kit for the Trijicon MRO is designed to solve a specific problem: getting a red dot optic into a repeatable, stable position that works with a helmet-mounted night vision device. GBRS Group built the Lerna around a co-witnessing philosophy—the mount positions the MRO so that the shooter can transition between naked-eye and NOD-assisted shooting without re-zeroing or dramatically shifting head position.

The mount uses a Cerakote finish in black, which provides corrosion resistance and a non-reflective surface suitable for field use. The construction is purpose-built rather than a generic riser, meaning the geometry is tailored to the MRO’s footprint and interface points rather than adapted from a universal platform. That specificity matters when you need a consistent return-to-zero after removing and reinstalling the optic.

This is a mount for a shooter who has already committed to the Trijicon MRO and wants a dedicated solution rather than a shim or adapter stack. It suits AR-pattern rifles and similar flat-top platforms where getting the optic height right relative to night vision optics is an operational consideration, not an aesthetic one. If your current setup requires you to compromise between a good cheek weld for daytime use and a workable sight picture under NODs, the Lerna is the kind of component that addresses that trade-off directly at the hardware level rather than through technique alone.
