GBRS Group FTC Magnifier Mount OMNI Magnifier Flat Dark Earth. 91 FTC (Flip-to-Center) elevates any magnifier to the 2.91 height for compatibility with the GBRS Group Hydra Mounting Systems. The 2.91 FTC Mount uses a straightforward force-to-overcome mechanism and tucks the magnifier below the optical sight plane fully within the weapon's receiver footprint when not in use. This design removes the need for flip-to-side placement seen in legacy products offering all the benefits of magnification when needed with no obstruction of sight pictures when stowed.
