  • Patent number: 8069604
    Abstract: A hand-guard and barrel nut clamping assembly for tactical firearms and other mechanical equipment that is subject to frequent or sustained vibration or shock, such as when a firearm is subjected to sustained rapid fire and/or the firearm is handled roughly. A small generally half-moon shaped anti-rotation clamping member is secured to a hand-guard support element or other suitable structure by socket head cap screws and is secured in frictional contact with components of the hand-guard mount and a barrel nut. The anti-rotation clamping member functions as a key to “tie” the barrel nut and hand-guard nut together, simultaneously preventing either one from rotating, and thus preventing inadvertent vibration or shock induced loosening of either the hand-guard retainer nut or the barrel nut. The anti-rotation clamping member is also keyed onto the front of the upper receiver by a slot into which a portion of the receiver is engaged.

  • Patent number: 7937877
    Abstract: A firearm has a body formed of a unitary first shell and a unitary second shell. Each shell defines an open cavity and has a peripheral rim. The rims of the shells are connected together so that the cavities define a receiver chamber. A bolt reciprocates within the receiver chamber, and a barrel connected to the shells has a chamber positioned for operable engagement by the bolt. The shells may together define a gas tube, and may define a barrel receiving element, each shell having a barrel engagement element. Each shell may have a side panel with flat portions having a limited thickness, and elongated ribs of a greater thickness. The ribs may extend about the periphery of planar side panels, and may extend between the periphery and selected stress elements on the body including a buttstock mounting facility. A bolt handle slot may have opposed rows of spaced apart bolt handle guides in an alternating arrangement.

  • Patent number: 7673413
    Abstract: A method for upgrading a non-recoil suppressing (NRS) stock to a special operations (Spec Ops) stock with full recoil suppression. The new parts are the slide member and lever that has a cam member mounted on its upper end and an extension spring attached to its bottom end. A locking pin is removed from the stationary slide member and two retainer pins are inserted from the sides into the new slide member to facilitate spring action. This structure functions in the same manner as the recoil reduction structure illustrated in U.S. Pat. No. 5,722,195. A replacement sleeve has a rib member extending downwardly from its bottom surface. Replacement sleeve and extension spring are assembled in a tubular member to form a second recoil reduction assembly. This recoil reduction structure functions in the same manner as the structure illustrated in U.S. Pat. No. 6,732,466.

  • Patent number: 7047686
    Abstract: An improved M1911-style handgun employs redistributed masses for a slide and bull barrel to reduce perceived recoil and muzzle flip when the gun is fired. The gun operates with cartridges having .50 caliber cases, bullets of .50 caliber or less, and 45 ACP-sized base rims, as well as with .45 ACP and smaller caliber cartridges. An improved magazine has crimped feed lips which feed rebated rim cartridges into any handgun or rifle without nose-diving, and a metal-reinforced follower which extends the operational life of the magazine.

  • Patent number: 6964123
    Abstract: In a low-cost firearm, the frame of the weapon comprises a laminated structure in which operative grooves and recesses having a base wall and one or more sidewalls are formed by laminating the sidewall to the base wall, so as to avoid the necessity for forming the grooves and recesses by performing expensive machining and finishing operations on a unitary frame structure. The sidewalls and the base walls are formed of separate materials that may be different from each other. For example one of the materials may be plastic, to provide light weight, while the other may be metal to achieve desired rigidity and/or strength. The laminations are coupled together by either mechanical members such as screws or rivets, or by bonding agents such as welding or high-strength adhesives or by a combination of both.

    Abstract: An apparatus and method for crowning a muzzle end of a firearm barrel includes inserting an elongated rod-like pilot stem with upper and lower ends into a barrel bore. The stem has an expandable collet slidably received thereon and a nut threadably attached to the lower end. A deformable body is attached to the nut to frictionally engage a bore wall to prevent rotation of the nut and permit rotation of the stem to expand the collet into contact with the bore wall. A cutting tool is rotated on the upper end of the stem to cut an end surface of the muzzle end.
