Abstract
A firearm barrel preloading device can preload threaded connections. The preloading device can include an outwardly facing barrel-contact surface, an outwardly facing receiver-contact surface, non-planar surfaces between the barrel-contact surface and the receiver-contact surface. The non-planar surfaces can include mated pairs of axisymmetric surfaces that cooperate to spread apart the barrel-contact surface and the receiver-contact surface when the preloading device is moved toward an expanded configuration.
Claims22
A firearm barrel preloading device, comprising:
- a barrel interface element;
- and
- a collar movable from an open configuration toward a dosed configuration while an end portion of a barrel extends through the collar, wherein the collar slidably contacts the barrel interface element such that the barrel interface element gradually applies increasing pressure to the barrel when the collar is moved toward the dosed configuration, thereby preloading a threaded connection between the barrel and a receiver.
A connection assembly installable on a firearm and movable from an unexpanded configuration to an expanded configuration to tension at least a portion of the barrel while a barrel is threadably coupled to a receiver, the connection assembly comprising:
- a receiver engaging element configured to contact the receiver;
- a barrel engaging element configured to contact the barrel;
- and
- a split collar with a first sloped surface and a second sloped surface, the first sloped surface slidably contacts a first axisymmetric surface of the receiver engaging element, and the second sloped surface slidably contacts a second axisymmetric surface of the barrel engaging element.
A firearm comprising:
- a receiver;
- a barrel;
- and
- a connection assembly movable from an unexpanded configuration for threadably coupling the barrel to the receiver to an expanded configuration to tension at least a portion of the barrel while the barrel is threadably coupled to the receiver.
A method for installing a barrel of a firearm, comprising:
- threadably coupling a barrel to a receiver;
- and
- moving a barrel preloading device from an installation configuration toward a preloading configuration to gradually apply pressure to a portion of the barrel to preload a threaded connection between the barrel and the receiver.
A method for tensioning at least a portion of barrel, comprising:
- threadably coupling a barrel nut to a barrel;
- threadably coupling the barrel to a firearm receiver;
- and
- adjusting the configuration of a tension control element to alter engagement between the tension control element and the barrel nut to adjust tensioning of a portion of the barrel between the barrel nut and the receiver.
A method for tensioning at least a portion of barrel, the method comprising:
- threadably coupling a barrel to a firearm receiver;
- and
- adjusting the configuration of a tension control element to alter engagement between the tension control element and the barrel to adjust tensioning of a portion of the barrel.
