GBRS Group 2.91 FTC Magnifier Mount Utilizing UNITY(TM) Tactical&';s revolutionary Flip-to-Center technology, the 2.91 FTC (Flip-to-Center) brings any magnifier to the 2.91 height to pair with the GBRS Group Mounting Systems. The 2.91 FTC Mount employs a simple 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 eliminates the flip-to-side placement of legacy products, in which users receive all the benefits of magnification when required with no occlusion of sight pictures when stowed.
