The Rotapoint Systems Gancho 30mm Scope Cap Offset Aimpoint ACRO Mount is a low-profile, lightweight mount that allows you to offset your Aimpoint ACRO footprint red dot sight from your 30mm scope. This an excellent solution for shooters who need to quickly transition between close-range and long-range targets. The Gancho mount features a 35 degree offset angle, which provides a clear view of the red dot without obstructing the magnification lever or ejection port. It is also designed to keep the red dot off the handguard allowing there to be more space for adding other accessories.
