The Geissele Super Precision extended cantilever Scope Mount (brand part no. 05-381B) is built for an AR-15/M4 upper that demands a scope mount holding zero shot after shot. The mounting surface spans 7 Picatinny rail sections and uses 4 shear lugs for rigidity, while Geissele’s update of the classic nut-and-bolt clamping method locks the mount to the rail with far more clamping force than a lever-style mount can offer.
