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 7):
A quick take-down firearm, comprising:\n (a) an upper receiver, the upper receiver comprising an upper receiver coupling; (b) a rifle barrel, the rifle barrel comprising a rifle barrel coupling, the upper receiver coupling and the rifle barrel coupling configured to secure the rifle barrel to the upper receiver; (c) a gas tube; and (d) a sliding lock collar, the rifle barrel and the gas tube extending through the sliding lock collar when the rifle barrel is secured to the upper receiver, the sliding lock collar slide-able towards and away from the upper receiver between a first position in which the rifle barrel can be removed from the upper receiver and a second position in which the rifle barrel cannot be removed from the upper receiver, the sliding lock collar biased toward the second position.
