1. A rail mounting assembly for mounting an accessory to a rail of a firearm comprising:
a base arranged to support the accessory;
a first side portion configured to engage a first side of the rail, the first side portion including a lock nut receiving recess;
a second side portion configured to engage a second side of the rail, the second side portion being opposite the first side portion and including a moveable clamp being movable relative to the first side portion such that the side portions cooperate to grip the rail;
a crossbar extending between the first side portion and the second side portion, the crossbar being movable relative to the moveable clamp;
a lock nut being threadably engageable to an end of the crossbar proximate to the first side portion, the lock nut extending at least partially into the lock nut receiving recess when threadably engaged to the end of the crossbar proximate to the first side portion;
a lock plate positioned within the lock nut receiving recess between the lock nut and a spring disk when the lock nut is threadably engaged with the crossbar;
a throw lever including a cam interconnected with a second end of the crossbar, the cam engaging the moveable clamp and being operable to pull the crossbar such that the side portions are moved from a released position to an engaged position, the throw lever being arranged to rotate the cam between an open and a closed position;
wherein the lock nut receiving recess is shaped to prevent rotation of the lock plate while allowing rotation of the lock nut.
