Abstract
A system for securing a barrel to a receiver of a rifle includes a barrel extension and a locking wedge. The barrel extension receives threads on the barrel and has a protuberance. The locking wedge is secured in an aperture in the receiver by a fastener. The locking wedge has a side parallel to the aperture, and a cam side disposed at an angle. The locking wedge is movable in a direction perpendicular to the barrel axis. The cam side is disposed against the protuberance. Tightening the fastener causes the cam side of the locking wedge to urge the protuberance of the barrel extension along the barrel axis in a direction away from the muzzle end of the barrel into the receiver.
Claims6
A system for securing a barrel to a receiver of a rifle, the barrel having a barrel axis, a muzzle end and a receiver end, the system comprising:
- (a) a barrel extension having a barrel end and a receiver end, said barrel extension having internal threads at its barrel end for receiving external threads on the barrel and a protuberance extending from a lower side of the barrel extension;
- (b) a locking wedge slidably secured in an aperture in the receiver by a threaded fastener, the locking wedge having a central aperture, a first side parallel to the central aperture, and a cam side opposite the first side and disposed at an angle relative to the first side, the locking wedge movable along an axis of the threaded fastener in a direction perpendicular to the barrel axis by rotating the threaded fastener, the cam side disposed against the protuberance;
- (c) wherein tightening the threaded fastener into the receiver causes the cam side of the locking wedge to urge the protuberance of the barrel extension along the barrel axis in a direction away from the muzzle end of the barrel and into the receiver;
- (d) wherein loosening the threaded fastener causes the cam side of the locking wedge to allow the barrel extension to move along the barrel axis in a direction toward the muzzle end of the barrel;
- whereby tightening the threaded fastener urges the barrel extension into the receiver, seating and aligning the barrel within the receiver.
A system for securing a barrel to a receiver of a rifle, the barrel having a barrel axis, a muzzle end and a receiver end, the system comprising:
- (a) a barrel extension having a barrel end and a receiver end, said barrel extension having internal threads at its barrel end for receiving external threads on the barrel and a protuberance extending from a lower side of the barrel extension, said barrel extension being tapered at the receiver end to mate with a corresponding tapered aperture in the receiver;
- (b) a locking wedge slidably secured in an aperture in the receiver by a threaded fastener, the locking wedge having a central aperture, a first side parallel to the central aperture, and a cam side opposite the first side and disposed at an angle relative to an axis of the central aperture, the locking wedge movable in a direction along an axis of the threaded fastener perpendicular to the barrel axis, the cam side disposed against the protuberance;
- (c) wherein tightening the threaded fastener into the receiver causes the cam side of the locking wedge to urge the protuberance of the barrel extension along the barrel axis in a direction away from the muzzle end of the barrel and into the receiver;
- (d) wherein loosening the threaded fastener causes the cam side of the locking wedge to allow the barrel extension to move along the barrel axis in a direction toward the muzzle end of the barrel;
- whereby tightening the threaded fastener urges the barrel extension into the receiver, seating and aligning the barrel within the receiver.
