Great quality. Makes it quick and easy to find sight picture. Pricey, but worth it.

Lerna for XPS2 by Chris Fisher, Verified Owner, June 27, 2026
I just put this on my Sig Rattler Canebrake. Phenomenal quality from the look and feel of it. Great mount height. I can comfortably reach shooting position without craning my neck. The Lerna makes it easy to immediately find good sigh picture.

Product Info for GBRS Group Lerna Red Dot Sight Mount

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.image
