AI Technical Summary

Benefits of technology

Enables quick and easy disassembly and reassembly of the rifle barrel from the upper receiver in the field, maintaining secure attachment and allowing the use of standard MILSPEC handguards and accessories, enhancing usability and versatility.

Problems solved by technology

AR-15, AR Pistols, M4, M16 and similar prior art MILSPEC rifles cannot be quickly disassembled and reassembled where the rifle barrel connects to the upper receiver, a process which usually requires the use of specialized tools and a work-bench equipped with a vise.
While there are some prior art systems that allow for in-field tool-less disassembly and reassembly of the barrel from the upper receiver, these systems are not effective or robust, are complicated to use, and do not allow for use of standard MILSPEC had guards and other accessories commonly used with these types of firearms.

of Use

[0101]The following is one example of a method of using the quick detach facility shown in

[0102]FIGS. 24-28B after installation onto a firearm.

[0103]Sliding lock collar 542 may be slid using a translational motion (e.g. non-rotational) back towards the upper receiver 10 to an unlocked position shown in FIGS. 28A & 28B that releases the locking elements 538 inside of the upper receiver coupling 532.

[0104]While the sliding lock collar 542 is held at the unlocked position, the barrel 12 may be inserted into the upper receiver 10. The barrel 12 is inserted until the barrel reference surface 28 contacts the upper receiver contact surface 22, with the barrel pin 30 seated in notch 20. During insertion of the barrel, gas tube 26 (or a piston) is also inserted through one of the tunnels 554 in the upper receiver coupling 532 and into opening 24 in the upper receiver 10. Once inserted, the locking element receivers 576 of the barrel coupling 534 are aligned with the locking elements 53...

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.
