Firearm rail mount

Abstract

A firearm rail mount has an elongated rail body having an upper surface defining a horizontal plane, the elongated rail body having lateral rail edges configured to be engaged by a scope ring base, the elongated rail body defining a channel transverse to the elongated rail body and open in an upward direction, the channel having a floor defining a floor plane, and the floor plane being angularly offset from the horizontal plane. The floor plane may be offset from the horizontal plane by 10-20 degrees. The floor plane may be offset from the horizontal plane by 1-44 degrees. The floor plane may be offset from the horizontal plane by 10-20 degrees. The elongated rail body may define a pattern of alternating blocks and gaps, and the channel is registered with one of the gaps. Each gap may include a bottom surface parallel to the horizontal plane.

I claim: 
     
         1 . A firearm rail mount for mounting a firearm optic having a reference surface, the mount comprising:
 an elongated rail body having an upper surface defining a horizontal plane;   the elongated rail body having lateral rail edges configured to be engaged by a scope ring base;   the elongated rail body defining a channel transverse to the elongated rail body and open in an upward direction;   the channel having a channel floor defining a floor plane; and   the floor plane being angularly offset from the horizontal plane.   
     
     
         2 . The mount of  claim 1  wherein the floor plane is offset from the horizontal plane by 1-44 degrees. 
     
     
         3 . The mount of  claim 1  wherein the floor plane is offset from the horizontal plane by 10-20 degrees. 
     
     
         4 . The mount of  claim 1  wherein the elongated rail body defines a pattern of alternating blocks and gaps, and the channel is registered with one of the gaps. 
     
     
         5 . The mount of  claim 4  wherein each gap includes a bottom surface parallel to the horizontal plane, and wherein the channel floor is adjacent to the bottom surface and meets the bottom surface at an obtuse angle. 
     
     
         6 . The mount of  claim 1  wherein the channel floor has a greater transverse length than does the bottom surface of the gap. 
     
     
         7 . The mount of  claim 1  including a plurality of channels spaced apart from each other and having a common floor plane. 
     
     
         8 . The mount of  claim 1  wherein the elongated rail body is a picatinny rail. 
     
     
         9 . The mount of  claim 1  including a planar tool having a first edge configured to engage the channel floor and a second edge configured to engage a reference surface of a riflescope rotatably received in the scope ring base, such that a tool angle between the first and second edges establishes a rotational position of the riflescope with respect to the rail mount. 
     
     
         10 . The mount of  claim 9  wherein the planar tool has a thickness established to be closely received within the channel. 
     
     
         11 . The mount of  claim 1  including a scope ring base connected to the elongated rail body and a riflescope with a cylindrical tube portion rotationally received by the scope ring base, and the riflescope having a reference surface facing the channel floor. 
     
     
         12 . The mount of  claim 1  formed integrally with a firearm receiver configured to receive operating firearm components including a bolt. 
     
     
         13 . The mount of  claim 1  including an attachment facility configured to removably connect the elongated rail body to a firearm frame. 
     
     
         14 . A method of connecting a scope to a firearm comprising:
 providing a firearm defining a horizontal reference plane, an alignment surface offset from the horizontal plane, and including a mount defining a cylindrical scope ring passage portion;   positioning a tubular portion of a riflescope having a reference surface, in the scope ring passage portion;   positioning a tapered tool having first and second edges acutely angled with each other between the alignment surface and the scope reference surface;   rotating the riflescope until the tapered tool is inserted a maximum amount and the first edge overlays the alignment surface and the second edge underlays the reference surface;   clamping the riflescope in the cylindrical scope ring passage portion to prevent rotation of the riflescope; and   removing the tapered tool.
