The Gbrs Group Lerna Mount Kit for Trijicon MRO puts your optic exactly where you need it—2.91 inches above your bore centerline. That height is the secret to running a rifle naturally: your head stays upright, your shoulders stay back, and your sight picture clears obstructions like comms headsets, gas masks, or night vision without forcing you into a compromised stance. Whether you're training hard, running duty gear, or building a serious fighting rifle, that extra elevation translates to faster target ID, better situational awareness, and the kind of athletic posture that lets your armor do its job.
Built from 6061-T6 aluminum with Type 3 hard coat anodize (FDE finish), the Lerna mount is robust and lightweight at 4.3 ounces. The clamp bar is 17-4 stainless steel with Melonite QPQ finish—corrosion-resistant and tough. All fasteners match: 17-4 PH stainless with Melonite, and 18-8 stainless washers. This is a purpose-built mount designed by shooters who understand that gear choices compound: higher optic, better posture, faster processing.
The kit ships with the tools you'll need: a long-reach T10 key, long-reach 3/32" hex key, and a quarter-inch drive T25 bit. Installation is straightforward, and the engineering is solid. If you're running a Trijicon MRO and want to optimize your sight picture and shooting position, the Lerna mount is the answer.

Yes. The 2.91" centerline height is specifically engineered to clear comms headsets, eye protection, gas masks, and night vision devices, allowing you to run those accessories without compromising your sight picture.
A higher optic centerline lets you maintain an athletic, upright posture with a vertical spine—the kind of stance that naturally presents body armor to a threat and enables faster target processing and situational awareness. You're not craning your neck down; the rifle meets you where you are.
The mount body is 6061-T6 aluminum with Type 3 hard coat anodize in FDE. The clamp bar, fasteners, and washers are stainless steel (17-4 PH and 18-8) with Melonite QPQ and Black Oxide finishes for corrosion resistance. The whole assembly weighs 4.3 ounces.
