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.

Claim (Index 17):
A barrel for a quick take-down firearm, the barrel comprising:\n (a) an insertion end configured for insertion into an upper receiver of the quick take-down firearm; (b) a raised reference surface on the barrel and a raised protrusion on the barrel, the reference surface and protrusion configured to align the barrel relative to the upper receiver when inserted into the upper receiver; (c) a barrel coupling comprising at least one depression configured to receive a locking element of the upper receiver coupling to secure the barrel to the upper receiver, the reference surface and protrusion located between the insertion end and the at least one depression; and (d) a handguard connector configured to secure a handguard of the quick take-down firearm to the barrel, the at least one depression located between the insertion end and the handguard connector.
