Abstract

An adaptive rail system 110 for a weapon 100 . An elongate body 141 is adapted to couple to a receiver cover 109 of the weapon 110 . A rail 130 extends from the body 141 . A front extension 134 also extends from the body 141 , the front extension being configured to be pivotably coupled to a sight housing 108 of the weapon 100.

1 . An adaptive rail system for a weapon, comprising:
 an elongate body, the body having a first distal end, an opposing second distal end, a first surface, and an opposing second surface, the rail body being configured to couple to a receiver cover of the weapon;   a rail extending away from the first surface of the rail body; and   a front extension extending from the first distal end of the rail body, the front extension being configured to be pivotably coupled to a sight housing of the weapon.   
     
     
         2 . The adaptive rail system of  claim 1  wherein the front extension further includes:
 a first outer hinge arm; 
 a second outer hinge arm spaced-apart from the first hinge arm; and 
 a center hinge arm disposed between the first and second outer hinge arms, 
 the first outer hinge arm, second outer hinge arm and center hinge arm being pivotably coupled to the sight housing of the weapon. 
 
     
     
         3 . The adaptive rail system of  claim 2  wherein the first outer hinge arm, second outer hinge arm and center hinge arm each include an aperture therethrough, the apertures each being aligned with one another. 
     
     
         4 . The adaptive rail system of  claim 3 , further including a retaining pin, the retaining pin extending through the apertures of the first outer hinge arm, the second outer hinge arm, the center hinge arm and at least one aperture of the sight housing of the weapon. 
     
     
         5 . The adaptive rail system of  claim 1  wherein the rail is a separate piece, the rail being joined to the rail body. 
     
     
         6 . The adaptive rail system of  claim 1  wherein the rail is integral to the rail body. 
     
     
         7 . The adaptive rail system of  claim 1  wherein the rail is one of a Picatinny-type rail and a Weaver-type rail, the rail being configured to detachably receive accessories for use with the weapon. 
     
     
         8 . The adaptive rail system of  claim 1 , further including a rail mount extending from the second distal end of the rail body, the rail mount being configured to couple to the receiver cover of the weapon. 
     
     
         9 . The adaptive rail system of  claim 8  wherein the rail mount is configured to slidably couple to the receiver cover of the weapon. 
     
     
         10 . The adaptive rail system of  claim 9  wherein the rail mount is configured to be selectably securable to the receiver cover of the weapon at a select position with respect to the receiver cover. 
     
     
         11 . The adaptive rail system of  claim 8  wherein the rail mount is selectably detachable from the rail body. 
     
     
         12 . The adaptive rail system of  claim 11 , further including:
 a pin projecting from a surface of the rail mount; and   a bore extending into the second distal end of the rail body, the bore being sized and shaped to slidably receive the pin.   
     
     
         13 . The adaptive rail system of  claim 11 , further including:
 a pin projecting from the second distal end of the rail body; and   a bore extending into the rail mount, the bore being sized and shaped to slidably receive the pin.   
     
     
         14 . The adaptive rail system of  claim 1  wherein the second surface of the rail body is shaped to receive the receiver cover of the weapon. 
     
     
         15 . An adaptive rail system for a weapon, comprising:
 an elongate body, the body having a first distal end, an opposing second distal end, a first surface, and an opposing second surface, the body being configured to couple to a receiver cover of the weapon;   a Picatinny-type rail extending away from the first surface of the body;   a front extension extending from the first distal end of the body, the front extension being configured to be pivotably coupled to a sight housing of the weapon; and   a rail mount extending from the second distal end of the body, the rail mount being configured to couple to the receiver cover of the weapon.   
     
     
         16 . The adaptive rail system of  claim 15  wherein the rail mount is configured to slidably couple to the receiver cover of the weapon. 
     
     
         17 . The adaptive rail system of  claim 16  wherein the rail mount is configured to be selectably securable to the receiver cover of the weapon at a select position with respect to the receiver cover. 
     
     
         18 . The adaptive rail system of  claim 15  wherein the rail mount is selectably detachable from the body. 
     
     
         19 . The adaptive rail system of  claim 15  wherein the second surface of the body is shaped to receive the receiver cover of the weapon. 
     
     
         20 . A method for adapting a rail system to a weapon, comprising the steps of:
 providing an elongate body, the body having a first distal end, an opposing second distal end, a first surface, and an opposing second surface, the body being configured to couple to a receiver cover of the weapon;   extending a rail away from the first surface of the body; and   extending a front extension from the first distal end of the body, the front extension being configured to be pivotably coupled to a sight housing of the weapon.
