Compatible with the Send iT MV3, this mount positions the MV3 vertically alongside the scope tube. It can be installed on either the left or right side of a section of picatinny rail. Ensure there is at least 0.3 inches of clearance between the scope tube and the top of the picatinny rail for proper installation. Please note that this mount is designed specifically for the MV3 model and does not accommodate the Send iT original or the XSL.
