Modular sleeve yoke

Abstract

A Swan universal receiver sleeve attached to the top of a firearm upper receiver and extended forward above the firearm barrel to a position just short of the firearm front sight. The underside of the rear portion of the sleeve is fixedly attached to the receiver top. The underside of the forward portion of the sleeve has an upper handguard piece attached thereto. A bottom handguard piece is fitted about the bottom of the gun barrel and is attached to the upper handguard piece. The handguard pieces are not physically connected in any way to the gun barrel. The sleeve is self supported by the connection of the rear portion underside to the receiver top. A special yoke is inserted about the barrel nut of the firearm to which the modular sleeve is attached. The special yoke reinforces the modular sleeve while keeping the firearm barrel free floating.

Description

[0001]This application is a C-I-P of Ser. No. 10 / 007,590 filed Dec. 10, 2001, which claims benefit of Prov. No. 60,274,147 filed Mar. 9, 2001.BACKGROUND OF THE INVENTION[0002]This invention relates to integration means, and more particularly to a device added to a firearm for incorporating ancillary equipment.[0003]As the field of combat and commercial weaponry expands, numerous add-on enhancements have become available for attachment to standard firearms thereby significantly upgrading the capability of the firearm. Various methods and means have been developed for interfacing the various add-on enhancements to firearms. Applicant's U.S. Pat. No. 5,142,806, incorporated herein by reference, discloses a universal receiver sleeve having an upper interface portion with standard, universal dimensions regardless of the firearm and having a lower interface portion specific to a particular firearm.[0004]Although the principles of the above identified patented device are generally applicab...

AI Technical Summary

Benefits of technology

[0008]To attain this, the present invention extends the Swan universal receiver sleeve forward above the firearm barrel to a position just short of the firearm front sight. A weaver type interface return portion may be provided on the underside of the sleeve, or left solid over the barrel in front of the receiver to accommodate solid handguards or modular, dovetailed handguards. The underside of the rear portion of the sleeve is fixedly attached to the receiver top. The underside of the forward portion of the sleeve has an upper handguard piece attached thereto. A bottom handguard piece is fitted about the bottom of the gun barrel and is attached to the upper handguard piece via a unique channel and track system. The handguard pieces are not physically connected in anyway to the gun barrel. The sleeve is self supported by the connection of the rear portion underside to the receiver top. L

Problems solved by technology

The problem with integrating laser technology to firearms is the inherent conflict between a gun barrel's physical functioning and the rigid environment required for laser operations.

The temperature of a gun barrel in use can rise to 900° F. This type of heat, as well as the physical shock on the gun barrel from firing, will quickly destroy la
