"The GBRS Group 2.91 FTC Magnifier Mount brings any magnifier to the ideal 2.91"" height to pair with the GBRS Group Hydra V2 or other mounting system. The 2.91 FTC (Flip-to-Center) Mount utilizes UNITY Tactical's force-to-overcome mechanism and stows the magnifier below the optical sight plane and completely within the footprint of the weapon's receiver when not in use. This is a significant improvement over the standard flip-to-side placement of traditional mounts because it won't interfere with your sight picture when stowed. The Magnifier Mount utilizes a quick-detach lever to connect to standard Picatinny rails. Each is crafted from 7075-T6 aluminum with a Type III hardcoat-anodized finish.
