AR-15/M16 INTEGRAL MOUNTING SYSTEM MARK 1/MARK 2 RAILS

Flattop-Mounted Bases

Machined aluminum mounts clamp directly to a MIL-STD 1913 Picatinny flattop rail to raise the scope and push it forward, eliminating the need for separate risers or specialized short eye relief optics. Slides into place and secures with steel crossbolts that hold tight. Eleven MIL-STD 1913 Picatinny cross-slots on top offer plenty of flexibility in ring spacing. Mark 1 locks into place on the receiver with two, flush-fitting T-15 Torx® screws. Mark 2 rail provides the same advantages as the Mark 1, with the added benefit of easy-to-grasp ½" hex nuts on the crossbolts for quick-release removal and re-install without loss of zero.
