GBRS Group ACRO Lerna Mount Kit Features The GBRS Group Lerna Mount Kit is machined from 6061-T6 aluminum and designed specifically around Aimpoint CompM5s and Duty RDS optics giving the shooter a mount built for the realities of duty and tactical use. The raised 2.91 inch optic centerline clears bulky gear such as ear protection communication headsets CBRN masks and night vision mounts that would otherwise interfere with a standard-height optic. That clearance means a faster more natural sight picture when transitioning between platforms or adding protective gear mid mission. The anodized black finish resists wear and corrosion while keeping the mount s profile low and snag-free on the weapon. Beyond the mount itself the kit includes a long reach T10 key a long reach 3/32 inch hex key and a 1/4 inch drive T25 bit so the user has every tool needed for installation without hunting down separate hardware. The elevated optic position encourages a more athletic heads-up shooting posture helping the shooter maintain a vertical spine that is more compatible with body armor and plate carriers. That posture translates directly into faster response times and improved situational awareness in dynamic encounters. Weighing only 4.0 ounces the GBRS Group Lerna Mount Kit adds minimal bulk while meaningfully improving optic accessibility for sale at GrabAGun.
