Firearm sight mount

A mounting apparatus for securing an sighting device to a rail on a firearm having a sighting axis, the apparatus comprising:

• a body having an axis;
• a rail attachment member carried by the body and configured to secure the body to the rail with its axis in alignment with the sighting axis;
• an sighting device attachment member configured to secure the sighting device to the body and the rail, the sighting device attachment member secured to the body by at least one pin riding in a groove in the sighting device attachment member, the sighting device attachment member being rotatable about the pin between an aligned position wherein the optical sight is above the rail on the firearm and aligned with the axis, and a offset position in which the sighting device attachment member and sighting device are laterally displaced from the aligned position;
• and
• at least one detent releasably securing the optics attachment member to the body in the aligned position, wherein the sighting device attachment member is moved out of the alignment position solely by pressure on the sighting device attachment member.

An apparatus for mounting a sighting device to a rail on a firearm in alignment with a sighting axis of the firearm, the apparatus comprising:

• a base configured for removable attachment to the rail, the base having a recess with generally opposing walls;
• a groove in each of the generally opposing walls;
• a sight base configured to receive and secure the sighting device, the sight base coupled to the base by a pin running in each of the grooves and rotatable about the pins between an aligned position with the base extending between the parallel walls and the sighting device aligned with the sighting axis, and a deployed position rotated away from the aligned position;
• and
• a detent mechanism extending between each of the walls and the sight base to releasably retain the sight base in the aligned position.

A mounting apparatus for securing a sight device to a rail aligned with a sighting axis of a firearm, the mounting apparatus comprising:

• a base having upper and lower extents, the upper extent being configured to receive and secure the sight device to the base;
• a clamp member carried on the lower extent of the base, the clamp configured to releasably engage the rail and having a portion selectively movable to tighten and secure the clamp and base to the rail;
• a lever pivotally coupled to the base and to the clamp member, the lever having a camming surface configured to move the movable portion of the clamp into and out of engagement with the rail in response to actuation of the lever;
• and
• a resilient surface carried by the base adjacent to the lever, wherein the camming surface of the lever bears on the resilient surface.
