A quick-detach barrel mounting system for removing and attaching a barrel to a receiver of a firearm. The quick-detach barrel mounting system can include a barrel nut having a body defining an axial bore. A proximal end of the barrel is received at least partially through the axial bore, and the barrel nut releasably engages a front end of the receiver. A hand guard can be mounted to the receiver and can define a cutout proximate the receiver. The hand guard at least partially encloses at least a portion of the barrel and the barrel nut, and the cutout is at least partially aligned with the barrel nut. At least a portion of the barrel nut is accessible via the cutout of the hand guard for at least partially disengaging and engaging the barrel nut with the receiver when the hand guard is mounted on the receiver.
