The Gbrs Group Lerna Mount Kit for EOTech optics delivers a higher sight picture that keeps your head up and your advantage sharp. Designed specifically for EOTech XPS red dot sights, the Lerna mount positions your optic at 2.91" above your rail—significantly higher than standard height setups. That extra elevation clears gear obstruction like communications headsets, gas masks, or night vision equipment, letting you stay behind your optic and your body armor without compromise. The result is faster target identification, better situational awareness, and the ability to maintain a vertical spine and athletic stance under pressure.

Built for professionals and serious operators, the Lerna combines precision engineering with rugged reliability. The mount body is 6061-T6 aluminum with hard coat anodize in black, while the clamp bar, fasteners, and hardware use 17-4 PH stainless steel with Melonite QPQ finish—materials chosen for durability in harsh conditions. Assembly is straightforward: the kit includes everything you need plus a T25 hex bit driver for installation on your EOTech XPS optic.

If you run night vision, magnification, or additional mounted gear on your upper receiver, the Lerna's elevated centerline prevents collision and allows you to employ backup iron sights or co-witness your primary optic without interference. The mount weighs just 4.2 oz, so it won't bog down your rifle's handling. Whether you're training for precision shooting, clearing buildings, or building a duty-ready carbine, the Lerna mount puts your optics where they belong—high, clear, and ready.

Frequently Asked Questions

Will the Lerna mount work with my EOTech XPS?

Yes. The Lerna mount kit is specifically designed for EOTech XPS red dot sights and includes the T25 hex bit driver necessary for installation on that platform.

Does the higher mount height clear night vision and gas masks?

That's exactly what the Lerna was designed for. The 2.91" optic centerline is engineered to sit above communications headsets, CBRN equipment, gas masks, and night vision mounted on standard helmet rails—so you can deploy your optic without removing or adjusting other gear.

What materials is the mount made from?

The Lerna body is 6061-T6 aluminum with hard coat anodize in black. The clamp bar, screws, and internal hardware use 17-4 PH stainless steel with Melonite QPQ finish, and washers are 18-8 stainless steel with black oxide passivation. These materials resist corrosion and perform reliably in field conditions.

How much does it weigh?

The Lerna mount kit weighs 4.2 oz, so it adds minimal weight to your rifle while providing the strength and durability needed for rigorous use.
