Picatinny riser designed for the Caliburn platform. Contains small sights built in. May work as a carry handle, but was not tested extensively nor designed for the purpose. Uses 6-32 x 1-1/4" countersink screw and hex nut, but can usually friction fit without it.

Added the ThiccBase variant, which adds more material to grip the rail with. This one uses a button head screw instead of countersink. You may need 6-32 x 1-1/2" however, not sure.
