Abstract: A firearm optic assembly has a body, the body having a first mounting facility configured to removably connect the body to the firearm, the body having a first receptacle configured to receive a first accessory, the body having a second mounting facility configured to removably receive a second mount portion associated with a second accessory offset from the medial plane, the second mounting facility including a pocket defined by one of the body and the second mount portion, the second mounting facility including a protrusion on the other of the body and the second mount portion, the protrusion being configured to be slidably or loosely received in the pocket, the protrusion having a free end and an opposed base end, the second mounting facility having an alignment facility including flared surfaces at the base end, and the flared surfaces being on opposing sides of the protrusion.

Abstract: A rifle scope mounting height assessment tool has a frame having a mounting facility configured to removable connect to the mounting facility of the rifle, a cradle movably connected to the frame and operable to move among a plurality of different vertical positions, the cradle defining a rifle scope support passage, and a retention element operable to secure the cradle relative to the frame in a selected one of the plurality of different vertical positions. The cradle may be constrained for only vertical translation movement with respect to the frame. The cradle may be moved only in translation with respect to the frame. The cradle may define an upwardly open channel. The rifle scope support passage may include a lower surface portion facing upward and configured to contact a lower surface of a cylindrical scope tube.

Abstract: A fixture for establishing a mounting position of a riflescope. The fixture comprises a base configured to connect to a rifle; the base having opposed standard extending upward and defining a passage configured to receive a rifle scope; a plurality of lateral apertures defined in each standard configured to removable receive lateral supports at a plurality of different levels; a plurality of lateral supports; and a retainer connected to the base and operable to bias the riflescope against the lateral supports.
