DEMO GBRS Group 2.91 FTC Magnifier Mount OMNI Black GEAR-FTCOMNI-BLK. 91 FTC (Flip-to-Center) brings any magnifier to the 2.91 height to pair with the GBRS Group Hydra 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. Compatibility: 30MM: Compatible with any magnifier with a 30mm body such as Aimpoint 3XMAG Aimpoint 3X-C and others Specifications for GBRS Group FTC Magnifier Mount: Manufacturer: GBRS Group Condition: New Fabric/Material: 7075 T6 Aluminum Finish: Type III Hardcoat Anodized Case Finish: Anodized Lead Free: No Application: Hunting Primer Style: Centerfire Package Contents: GBRS Group FTC Magnifier Mount GBRS Group GEAR-FTCOMNI-BLK: 2.91 FTC Magnifier Mount OMNI Black
