Picatinny rail, short w/ 6 slots, but 4 usable ones. Limited range of positioning for the cross bolt, but a clamp-on attachment should be able to utilize this rail completely.

Rail clearance: 4mm.
The Picatinny railing complies fully to MIL-STD M1913.
Supplied w/ 2x 2.9x18mm self-tapping panhead screws. We recommend drilling pilot holes first, prior to installing these screws.
