Embodiment Construction

[0032]Referring now to the drawings and first to the elevational view of FIG. 1, there is shown a tactical firearm generally at 10 embodying the principles of the present invention. The firearm 10, is preferably in the form of a tactical rifle of relatively heavy bore, such as being chambered for the 7.62 mm United States Military cartridge, also referred to as the .308 caliber rifle cartridge. However, it should be borne in mind that the present invention is applicable to firearms of both lighter and heavier bore without departing from the spirit and scope of the invention. For purposes of simplicity, though the scope of this invention encompasses a wide range of firearm devices, the invention is referred to herein as a tactical rifle.

[0033]The tactical rifle 10 incorporates an upper receiver 12 to which a lower receiver 14 is pivotally mounted by means of a pivot pin 16 which extends through corresponding pivot openings of the lower receiver 14 and a pivot opening 18 of a downward...

Abstract

A tactical firearm having a receiver and a handguard connected by flanges that are secured by fasteners and each define co-planar rail mounting surfaces. A one-piece elongate sight mounting rail extends along the combined length of the receiver and handguard and has a mounting surface in face to face relation with the rail co-planar rail mounting surfaces of the receiver and handguard. The rail is tapered along its length to provide an angle of cant and to permit mounting sight devices an any desired location along its length. A barrel extends through the handguard and is secured to the receiver in a manner achieving clearance and thermal isolation of the handguard from the barrel and barrel retainer. A cartridge gas energized bolt carrier and bolt mechanism is moveable within the receiver and is provided with anti-tilt guidance with respect to a spring energized buffer mechanism and moves a cartridge from a magazine into the cartridge chamber of the barrel and returns the bolt mechanism to its closed and locked condition upon dissipation of the cartridge gas energizing force.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to firearms and more particularly to semi or full automatic tactical firearms such as rifles. More particularly, the present invention concerns a tactical rifle that may be provided with semiautomatic and full automatic cartridge loading, firing and ejecting capability and is designed specifically for use of a relatively heavy bulleted cartridge such as the .308 which has a bullet diameter of 7.62 mm. The present invention also concerns a tactical firearm having heat shielding properties to minimize the transfer of heat from the barrel to the handguard such as during sustained rapid fire activities. Even more specifically the high accuracy tactical firearm of the present invention is designed with a continuous mounting rail having a desired angle of taper or cant to receive pivot actuated locking mounts of the type that is set forth in U.S. Pat. No. 7,272,904 of Mark C. LaRue and ...
