Abstract
A device and method for stabilizing a rifle scope that employs a pocket cut in the bottom of a scope base (picatinny rail) that precisely mates with a key formed on the top of a recoil lug, such that when the scope base is attached to the rifle's action receiver and mated with the lug's key, the lug holds the barrel and the scope base locked in tandem so that they move exactly together during recoil events or any vibrations experienced by the rifle.
Claims15
A recoil device for a rifle comprising:
- a lug configured to sit in line between a barrel and an action receiver, said lug having a top, the action receiver having a dorsal surface, and the top of the lug comprising a key;
- and
- a rail configured to attach to the dorsal surface of the action receiver, the rail having a bottom, and the bottom of the rail comprising a keyseat to receive the key;
- wherein, when the key mates with the keyseat, the key holds the rail in tandem with the lug and restricts its movement in a forward and backward direction relative to the barrel's direction of firing.

A device for a rifle comprising:
- a washer and a picatinny rail,
- the washer configured to sit between a barrel and an action receiver, said washer having a protrusion on at least one side;
- the rail having a bottom, the protrusion configured to fit into a pocket in the bottom of the rail;
- wherein, when the protrusion mates with the pocket, the protrusion holds the rail in tandem with the washer in a forward and rearward direction relative to the barrel's direction of firing.
1 more element
A rail for attaching a scope to a rifle comprising:
- a rail, having a bottom, the bottom of the rail further comprising a keyseat having a geometric shape configured to receive a matching key of a recoil lug, wherein when the recoil lug having a matching key is positioned between an action receiver and a barrel, with the key positioned above a dorsal surface of the action receiver and the rail is seated on an action receiver, the key is inserted in the keyseat, and the key restricts movement of the rail in every horizontal direction relative to the key, the barrel, and the action receiver.
A method for maintaining the calibration of a rifle scope on a rifle comprising:
- positioning a lug on a threaded end of a barrel between the barrel and an action receiver,
- the lug configured to sit in line between a barrel and an action receiver, said lug having a top, the action receiver having a dorsal surface, and the top of the lug comprising a key;
- and
- fastening a rail to the dorsal surface of the action receiver using fasteners, the rail having a top and a bottom, and a pocket located in the bottom of the rail to receive the key,
- wherein the key mates with the pocket of the rail when the rail is fastened to the action receiver thereby connecting the rail to the barrel by holding the rail in tandem with the lug and restricting the rail's movement in a forward and backward direction relative to the barrel's direction of firing.
