Ruger 10/22 Picatinny Rail

Picatinny Rail for standard Ruger 10/22, uses all four mounting holes. May fit other models, I don't know. Arc on bottom is a bit too pronounced to sit flat on the receiver, I will update model when I have a chance.

Upadated 12/27/17: Reduced height of rail so it now works with the mounting screws included with the gun. Also fixed the angle of the arc. The rail sits nice and flat against the receiver now.
