LERNA OPTIC MOUNT KIT FOR Eotech EXPS FDE$174.00
Availability: In Stock
The GBRS Group Lerna Optic Mount Kit for Eotech EXPS is a purpose-built riser that solves a real problem: raising your red dot sight above the clutter of modern tactical gear. Whether you're running comms headsets, ear protection, night vision, or gas mask-compatible equipment, the Lerna positions your optic at a 2.91" centerline—high enough to clear obstructions while keeping your sight picture fast and natural. This isn't a marginal tweak; it's the difference between maintaining a vertical spine under body armor and contorting yourself behind your rifle.
Built by GBRS Group, a team that understands how gear actually gets used in the field, the Lerna prioritizes what matters: repeatable mounting, reliable materials, and an ergonomic stance that keeps your head up and your awareness sharp. A higher optic centerline directly translates to faster target identification and quicker processing—advantages that compound in high-stress scenarios. The "heads up" posture it enables isn't just comfortable; it's tactically sound, letting you maintain better situational awareness and a stronger defensive position.
The mount itself is built from 6061-T6 aluminum with Type 3 hard coat anodize, paired with stainless steel clamp bars and hardware finished in Melonite QPQ for corrosion resistance. At 4.0 ounces for the Eotech EXPS version, it adds minimal weight while delivering the kind of material quality and finish that won't degrade after hard use. Everything needed for installation is included, so you can mount your EXPS and get to work.
