20110061523 | Semi Bolt Receiver Assembly for assembly with a Semi Automatic Rifle Base - A new and useful a semi bolt receiver assembly is provided, that configured for assembly with a rifle base that has a buttstock and pistol grip configured for semi automatic operation. The semi bolt receiver assembly includes a receiver, a bolt and carrier assembly, and a manually operable handle that is coupled with the bolt and carrier assembly in a manner that enables the bolt and carrier assembly to be manipulated by a shooter to charge the rifle (i) while the shooter is maintaining a shooting position and (ii) without removing the shooter's hand from the pistol grip. The semi bolt receiver assembly is particularly useful when configured for assembly with an AR-15 rifle base. | 03-17-2011 |
20110146484 | RIFLE STRIKING MECHANISM FOR SEMI-AUTOMATIC OPERATION - A striking mechanism for the semi-automatic operation of a cartridge firing firearm includes a receiver, a barrel attached to the receiver and providing a breach, an op rod assembly, and a bolt adapted for reciprocating movement within the receiver and engagable with the breach of the barrel and the face of a cartridge chambered therein. The bolt carries a primary firing pin, and a bolt lock means is pivotally connected to the bolt for selectively locking the bolt within the receiver. A bolt link assembly is pivotally connected to the bolt lock means and to the op rod assembly. The bolt link assembly provides a bolt link transfer pin. An op rod transfer pin is carried by the op rod assembly and can engage the bolt link transfer pin. A linear hammer can engage the op rod transfer pin such that, when a cartridge is chambered and the primary firing pin, the bolt link transfer pin and the op rod transfer pin are in alignment, the force of the linear hammer engaging the op rod transfer pin is transferred through the op rod transfer pin, the bolt link transfer pin and the primary firing pin to strike the primer of a cartridge chambered within the barrel. The striking mechanism is incorporated into prior art fully-automatic firearms to convert them to semi-automatic operation, and methods for such conversion are included. | 06-23-2011 |
20110168008 | M240 RIFLE WITH SELECT FIRE MECHANISM FOR SELECTIVE FULLY-AUTOMATIC AND SEMI-AUTOMATIC OPERATION - A trigger assembly for a trigger housing for an M240 Assault Rifle is provided having a switch accessible at the outside of the trigger housing for changing the firing of the rifle between semi-automatic and fully-automatic fire. | 07-14-2011 |
20110252957 | MODIFIED BOLT ASSEMBLY WITH FORWARD ASSIST ADAPTOR FOR ACCOMODATING SUB CALIBER AMMUNITION UTILIZED IN AN AR-15 TYPE FIREARM - A sub caliber action device installable within an upper receiver of an AR-15 type firearm which interfaces with an upper receiver mounted forward assist for use with such as .22 caliber ammunition. The device includes a generally elongated receiver plate exhibiting a generally lengthwise extending notched interior established between extending sides, with the notched interior seating a bolt and a forward assist adaptor in reciprocating fashion along the receiver plate between an end-most location and a forward secured chamber adaptor. The adaptor is reconfigurable to inertially and linearly displace a limited distance relative to the bolt support sleeve during full auto firing mode and which influences the bolt against the chamber adaptor during striking of the bolt supported firing pin by the hammer. | 10-20-2011 |
20110265638 | CHAMBER INSERT LOCK INSTALLED WITHIN AN AR-15/16 BARREL EXTENSION FOR LOCATING AND REDUCING MOVEMENT OF AN ASSOCIATED SUB CALIBER ACTION - The present invention teaches an insert locking mechanism incorporated into a sub caliber action device, installable within an upper receiver of an AR-15 type firearm, and which interfaces with an upper receiver mounted forward assist for use with such as .22 caliber ammunition and in order to eliminate movement or play of the chamber insert adaptor associated with the substituted sub caliber action. The mechanism includes a generally cylindrical shaped body supported upon the action and exhibiting a plurality of radially projecting and circumferentially extending lugs which are configured to mate and seat within a plurality of grooves circumferentially arrayed within a barrel defined in the upper receiver. | 11-03-2011 |
20110315002 | TRIGGER-CONTROLLED SELECT FIRE FOR M-16 RIFLE - A trigger system for a firearm has an enclosure having a bottom surface, a trigger pivoted at a first pivot axis within the enclosure, a firing hammer pivoted at a second pivot axis within the enclosure, the firing hammer spring-loaded to rotate clockwise to fire, the firing hammer having a first notch, a disconnector pivoted at the first pivot axis, the disconnector rocker having a hook for engaging the first notch in the firing hammer preventing firing while engaged, and a full auto rocker pivoted at a third pivot axis through the trigger, the full auto rocker having a first portion extending downward and forward from the third pivot axis and a second portion extending rearward from the third pivot axis, a part of the second portion overlying a contact point on the disconnector to the rear of the first pivot axis. | 12-29-2011 |
20120144992 | M249 RIFLE WITH SELECT FIRE MECHANISM FOR SELECTIVE FULLY-AUTOMATIC AND SEMI-AUTOMATIC OPERATION - A trigger assembly for a trigger housing for a, M249 fully automatic rifle is provided having a switch accessible at the outside of the trigger housing for changing the firing of the rifle between semi-automatic and fully-automatic fire. | 06-14-2012 |
20120144993 | M60 RIFLE WITH SELECT FIRE MECHANISM FOR SELECTIVE FULLY-AUTOMATIC AND SEMI-AUTOMATIC OPERATION - A trigger assembly for a trigger housing for a, M60 fully automatic rifle is provided having a switch accessible at the outside of the trigger housing for changing the firing of the rifle between semi-automatic and fully-automatic fire. | 06-14-2012 |
20120204712 | DUAL ACTION SHOTGUN - The dual action shotgun includes a receiver that has an auto-loading mechanism coupled to a magazine. The magazine extends outwardly from the receiver to facilitate sliding movement of an action arm thereon relative to the receiver. A manually operable foregrip also slidable along the magazine is positioned to manually operate the action arm to prepare a cartridge and the firing mechanism of the shotgun independent of the operation of the auto-loading mechanism. | 08-16-2012 |
20150308785 | FIREARM BUMP STOCK ASSEMBLY - A firearm bump stock assembly provides a mount and support for a conventional semi-automatic firearm. The firearm bump stock assembly beneficially provides a user with the ability to increase the fire rate efficiency of a firearm by reducing the amount of time between pulling of a trigger on a firearm and reloading of a new bullet into a chamber of said firearm, thus allowing said firearm to be reloaded and fired more rapidly. The firearm bump stock assembly also beneficially provides a user with the ability to maintain accuracy of said firearm and to easily aim and maneuver said firearm, while concurrently being able to increase said firearm's rate of fire. | 10-29-2015 |
