US12332022 - Optics mount and riser system for a firearm

An optic mount modular system includes a bridge portion that is mounted on the top rail of a firearm. The bridge portion can have either an integral optics riser on which a sight can be mounted, or a top rail section. The bridge portion has a front end and a rear end, each of which have a vertical face in which there is a horizontal bore. At the top of the bridge portion at the front and rear ends there are horizontal interfaces or surfaces in which there are vertically oriented threaded bores. Accessories such as rail extension portions and magnifier mounts can be mounted to the bridge portion at the front and rear ends. These accessories can include an alignment pin or protrusion than extends from a vertical face that mates against the vertical face at the front end or rear end of the bridge portion, and the alignment pin or protrusion will fit into the horizontal bore of the front or rear end. The accessories also have a tongue that extends over the top of the bridge portion at the front end or rear end, and a threaded fastener passes through an opening in the tongue that is aligned with the vertical threaded bore in the bridge portion. A threaded fastener can then securely attach the accessory to the bridge portion.
