Firearm accessory mounting interface

Abstract

An accessory mounting interface for a firearm, and a related method, are disclosed. The interface has a firearm accessory, a first elongated fastener, and a second fastener rotationally mated to the first elongated fastener. The first elongated fastener has right-handed threading and is arranged through a through hole in the firearm accessory with a first end extending below first and second halves of a first slot protrusion of the firearm accessory. The second fastener has a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener having a plurality of straight edges. At least one of the plurality of straight edges prevents the second fastener from rotating further than a closed position when the at least one of the straight edges abuts a sidewall of an elongated slot in the firearm.

What is claimed is: 
     
         1 . An accessory mounting system for a firearm comprising:
 a mounting surface defining a slot having a first end and a second end;   an accessory comprising a first protrusion and a second protrusion, the accessory defining a hole extending through the first protrusion;   a first fastener having an elongated body; and   a second fastener defining a hole;   wherein:
 the elongated body of the first fastener is configured to extend through the hole of the accessory and through the hole of the second fastener; 
 the elongated body of the first fastener and the second fastener are configured to extend through the slot of the mounting surface and couple the accessory with the mounting surface; 
 the first protrusion of the accessory is configured to sit within the slot and abut the first end of the slot; and 
 the second protrusion of the accessory is configured to sit within the slot and abut the second end of the slot.
