Mounting your Send iT MV3 leveling tool has never been easier, thanks to Long Range Arms' MV3-90 Mount. This allows you to mount the tool vertically on both sides of the scope tube, so it's perfect for left- and right-handed shooters. All you need is a short section of Picatinny rail, and this mount is so trim, you only need .3 inches of clearance between the tube and Picatinny rail to mount the unit. Be aware, though, that this mount does not work with previous versions of the Send iT leveling tool, only the MV3 model. Mfg: Long Range Arms
