Mounting base and rings for mounting an optical scope to a rocket propelled grenade (rpg) launcher

Abstract

An optical scope mounting system is disclosed including a back-sloped base mount and a pair of rings, to cooperate with the base mount, for positioning an optical scope laterally of the weapon on which it is mounted. The optical mounting system finds utility on rocket propelled grenade (RPG) launchers. The back-sloped base mount creates a divergence between the centerline of the bore of the RPG launcher and the line of sight through the optical scope.

What is claimed is: 
     
         1 . An optical scope mounting system for a rocket propelled grenade (RPG) launcher, the system comprising:
 a rail mount, the rail mount having a lower surface shaped to be complementary to an exterior surface of the barrel of the RPG launcher and to be mounted over and in-line with a bore of the RPG barrel,   the rail mount having an upper surface to accept a pair of rings configured to receive the optical scope;   a pair of rings, each ring of the pair of rings having a base configured to engage with the rail mount and a portion to receive the optical scope; and   wherein the rail mount is shaped so as to be back sloped in a direction opposite to a muzzle of the bore.   
     
     
         2 . The optical scope mounting system according to  claim 1 , wherein a connecting portion of the rings between the base and the portion to receive the optical scope is shaped to position the optical scope offset from, and laterally of, the bore of the RPG. 
     
     
         3 . The optical scope mounting system according to  claim 1 , wherein the upper surface of the rail mount has a Picatinny configuration. 
     
     
         4 . The optical scope mounting system according to  claim 1 , wherein the rail mount has a dovetail portion. 
     
     
         5 . The optical scope mounting system according to  claim 4 , wherein the base of the rings have a shape to engage the dovetail of the base. 
     
     
         6 . The optical scope mounting system according to  claim 5 , wherein the shape on the base of the rings is adjustable so as to clamp on the dovetail of the base. 
     
     
         7 . The optical scope mounting system according to  claim 2 , wherein the connecting portion is shaped so as to position the optical scope parallel to the bore of the RPG launcher, but at a position both laterally away from and above the bore of the RPG launcher. 
     
     
         8 . The optical scope mounting system according to  claim 7 , wherein the connecting portion terminates in a semi-circular open ended shape. 
     
     
         9 . The optical scope mounting system according to  claim 8 , further comprising a mating cap portion to join the connecting portion which terminates in a semi-circular open ended shape. 
     
     
         10 . The optical scope mounting system according to  claim 9 , wherein the mating cap portion is joined to the connecting portion which terminates in a semi-circular open ended shape by threaded fasteners. 
     
     
         11 . A rocket propelled grenade (RPG) launcher in combination with the optical scope mounting system according to  claim 1 . 
     
     
         12 . The rocket propelled grenade (RPG) launcher in combination with the optical scope mounting system according to  claim 11 , further comprising an optical scope. 
     
     
         13 . The optical scope mounting system according to  claim 6 , wherein the shape on the base of the rings is adjustable so as to clamp on the dovetail of the base comprises a complementary half dovetail shape and a variable screw member. 
     
     
         14 . The optical scope mounting system according to  claim 13 , wherein the variable screw member comprises a threaded stud and a thumb nut. 
     
     
         15 . The optical scope mounting system according to  claim 1 , wherein the rail mount is comprised of steel. 
     
     
         16 . The optical scope mounting system according to  claim 1 , wherein each of the rings is comprised of steel.
