Mount assembly for interchanging optical sights

Abstract

Implementations of a mount assembly for interchanging optical sights on a pistol are provided. In some implementations, the mount assembly comprises an adaptor plate and a pistol slide having an adaptor interface. In some implementations, the adaptor interface of the pistol slide is configured to receive an adaptor plate therein. In some implementations, an optical sight may be secured to the adaptor plate. In some implementations, a dovetail configured to receive a rear sight is positioned between the ejection port and the adaptor interface of the pistol slide. In this way, iron sights may be used in conjunction with some implementations of the mount assembly disclosed herein.

1 . A mount assembly for securing an optical sight to a pistol, the mount assembly comprising:
 a slide for use with a pistol, the slide having an adaptor interface, the adaptor interface comprising end walls and a bottom surface, wherein the bottom surface is recessed below the top of the slide;   an adaptor plate configured to be received by the adaptor interface, the adaptor plate comprising one or more openings therethrough and a mounting surface configured to receive an optical sight thereon; and   one or more screws;   wherein the mounting surface is located on a top side of the adaptor plate and the one or more openings are each configured so that one of the one or more screws may be inserted therethrough from a bottom side of the adaptor plate.   
     
     
         2 . The mount assembly of  claim 1 , wherein the one or more openings of the adaptor plate are positioned thereon to align with a corresponding number of threaded openings located on a bottom side of an optical sight when the optical sight is positioned on the mounting surface of the adaptor plate. 
     
     
         3 . The mount assembly of  claim 2 , wherein the one or more openings of the adaptor plate number four. 
     
     
         4 . The mount assembly of  claim 2 , wherein the mounting surface is a relief within the top side of the adaptor plate. 
     
     
         5 . The mount assembly of  claim 2 , wherein the adaptor plate further comprises a tab extending from a bottom side thereof. 
     
     
         6 . The mount assembly of  claim 5 , wherein the slide further comprises a tab relief that extends from an edge of the bottom surface of the adaptor interface along a side of the slide, the tab relief is configured to receive the tab of the adaptor plate therein. 
     
     
         7 . The mount assembly of  claim 6 , wherein the tab has an opening extending therethrough and the tab relief has a threaded opening therein, the opening of the tab is in axial alignment with the threaded opening of the tab relief. 
     
     
         8 . The mount assembly of  claim 2 , further comprising a recoil lug on the mounting surface of the adaptor plate. 
     
     
         9 . The mount assembly of  claim 2 , wherein the slide further comprises an ejection port and a dovetail, the dovetail is configured to receive a rear sight therein and is located between the ejection port and the adaptor interface of the slide. 
     
     
         10 . The mount assembly of  claim 2 , wherein the end walls and the bottom surface of the adaptor interface form a female portion of a dovetail joint. 
     
     
         11 . The mount assembly of  claim 10 , wherein the ends of the adaptor plate form a male portion of a dovetail joint. 
     
     
         12 . A method of securing an optical sight to the slide of a pistol using the mount assembly of  claim 2 , the method comprising:
 positioning an optical sight on the mounting surface of the adaptor plate;   inserting one of the screws through each of the one or more openings of the adaptor plate from the bottom side thereof;   securing each of the screws into a corresponding threaded opening located on the bottom side of the optical sight thereby securing the optical sight to the mounting surface of the adaptor plate; and   inserting the adaptor plate into the adaptor interface;   wherein the adaptor plate positions the optical sight on the slide of a pistol for use by a user.   
     
     
         13 . The method of  claim 12 , wherein the adaptor plate further comprises a tab extending from a bottom side thereof and the slide further comprises a tab relief therein, the method further comprising:
 positioning the adaptor plate so that the tab is on the same side of the slide as the tab relief; and   inserting the adaptor plate into the adaptor interface so that the tab comes to rest within the tab relief.   
     
     
         14 . The method of  claim 12 , wherein the slide further comprises an ejection port and a dovetail, the dovetail is located between the ejection port and the adaptor interface, the method further comprising:
 inserting a rear sight into the dovetail of the slide.
