Abstract
Quick take-down firearms and methods of using quick-take down firearms. The quick-take down includes an upper receiver coupling and a barrel coupling. The quick take-down can be unlocked by sliding a sliding lock collar in a translational motion to an unlocked position to release locking elements from a locked configuration. In the unlocked position, a barrel and handguard may be installed onto and removed from the upper receiver of the firearm. Releasing the sliding lock collar returns it to a locked position, securing the barrel and handguard to the upper receiver.
Claims28
A method of assembly for a quick take-down firearm, the method comprising:
- (a) sliding a lock in a translational motion from a locked position to an unlocked position to release a plurality of locking elements from a locked configuration, wherein a resilient member biases the lock away from the unlocked position towards the locked position;
- (b) inserting an end of a barrel of the firearm into an upper receiver of the firearm, seating an alignment protrusion into an alignment protrusion receiver, and connecting a gas tube of the barrel to the upper receiver;
- and
- (c) after inserting the end of the barrel into the upper receiver, allowing the resilient member to slide the lock to the locked position to return the plurality of locking elements to the locked configuration, securing the upper receiver to the barrel.
The method of claim 5, wherein the at least one depression comprises a plurality of depressions around the barrel.
The method of claim 5, wherein seating the alignment protrusion comprises seating an alignment pin of the barrel into a notch, the alignment pin and the notch limiting the rotation of the barrel relative to the upper receiver.
A quick take-down firearm, comprising:
- (a) an upper receiver;
- (b) a barrel;
- (c) a handguard secured to the barrel;
- and
- (d) a lock collar configured to secure and release the barrel from the upper receiver, the lock collar translatable between a locked position in which the barrel and handguard are secured to the upper receiver and an unlocked position in which the barrel and handguard are removable from the upper receiver, the lock collar being biased towards the locked position by a resilient element, the lock collar located between the upper receiver and the handguard and extending around the barrel when the barrel and handguard are secured to the upper receiver.
A barrel extension for a quick take-down firearm, the barrel extension comprising:
- (a) on an exterior of the barrel extension, an insertion surface configured for insertion into an upper receiver of a quick take-down firearm, a reference surface configured to limit a depth of insertion of the insertion surface into the upper receiver, an alignment protrusion configured to rotationally align the barrel extension relative to the upper receiver, and at least one depression configured to receive one or more locking elements of a quick-take down coupling of the upper receiver;
- (b) in an interior of the barrel extension, a cavity extending through the barrel extension, and a plurality of bolt lugs extending into the cavity;
- and
- (c) the barrel extension configured for attachment to an elongated barrel.
A barrel for a quick take-down firearm, the barrel comprising:
- (a) on an exterior of the barrel, an insertion surface configured for insertion into an upper receiver of a quick take-down firearm, a reference surface configured to limit a depth of insertion of the insertion surface into the upper receiver, an alignment protrusion configured to rotationally align the barrel relative to the upper receiver, and at least one depression configured to receive one or more locking elements of a quick-take down coupling of the upper receiver;
- (b) in an interior of the barrel, a cavity having a plurality of bolt lugs extending into the cavity, a chamber configured to receive a round of ammunition, and an elongated bore extending from the chamber;
- and
- (c) wherein the barrel is configured to secure a handguard of the firearm.
