Publication number: 20220214127Abstract: An electronic trigger system with safety mechanism for firearms includes a trigger unit comprising an electromagnetic actuator operably coupled to the firing mechanism and a programmable trigger mechanism microcontroller. The actuator is changeable between a non-powered unactuated position and powered actuated firing position via pulling both an outer trigger and inner safety trigger of the trigger unit. The actuator is operably interfaced with a movable firing component of the firing mechanism operable to discharge the firearm. In a blocking position of the safety trigger, the safety trigger is configured to block outer trigger movement which prevents energizing and actuating the electromagnetic actuator thereby preventing the firearm from discharging.Type: ApplicationFiled: March 28, 2022Publication date: July 7, 2022Inventors: John M. French, Louis M. Galie, Robert Gilliom, Gary Hamilton, John Klebes, Rafal Slezok, Scott Warburton

Patent number: 11112201Abstract: A barrel porting system for a firearm in one embodiment includes a barrel defining an axially extending barrel bore, a porting device coupled to the barrel and including a plurality of gas portholes in fluid communication with the barrel bore, and an outer shroud encircling at least the porting device. The shroud includes at least one gas discharge port arranged to vent combustion gas from firing the firearm in an outwards direction. An annular gas collection plenum formed between the shroud and porting device is configured to collect gas from the gas portholes and discharge the gas through the at least one discharge port in the shroud. In one implementation, the plenum is formed by a recessed channel in the muzzle device which extends around the entire circumference of the device. Various threaded and unthreaded coupling methods may be used to secure the muzzle device to the barrel.Type: GrantFiled: July 29, 2020Date of Patent: September 7, 2021Inventor: Scott Warburton

Patent number: 10309736Abstract: A shell loading system for a firearm in one embodiment includes a barrel, receiver, reciprocating slide and bolt assembly, tubular magazine, tilting carrier operable to receive and feed shells from the magazine into the action, a spring-biased carrier latch laterally moveable to engage the carrier, and a pawl pivotably mounted on the carrier. A carrier latch disconnect is movable between an unblocking and blocking position that prevents engagement of the carrier latch with carrier. To prevent bouncing of the carrier after firing a shot, a first detent feature on carrier assembly automatically engages a second detent feature in the receiver as the carrier returns downward from an upward position when the action is cycled by discharging the firearm. The detent features automatically disengage when the slide moves rearward to permit normal operation of the carrier when cycling the action.Type: GrantFiled: September 20, 2017Date of Patent: June 4, 2019Inventors: Scott Warburton, Bruce Rozum, Jason Pittman

Patent number: 9476660Abstract: A firearm with safety mechanism in one embodiment comprises a receiver, a trigger-actuated firing mechanism with movable trigger operable to discharge the firearm, and a safety mechanism configured to arrest the firing mechanism. The safety mechanism is movable between a first position preventing movement of the trigger and a second position allowing movement of the trigger for discharging the firearm. In one embodiment, an elongated stock bolt attaches a buttstock to the receiver. The stock bolt passes through a portion of the safety mechanism to engage the receiver. This allows an operating button of the safety to be ergonomically mounted on a top surface of the firearm above the stock bolt. In one implementation, the firing and safety mechanisms may each be operably mounted in a fire control module disposed in the receiver and removable therefrom as a separate self-supported unit.Type: GrantFiled: June 25, 2015Date of Patent: October 25, 2016Inventors: Dwight Potter, Jason Pittman, Scott Warburton

Patent number: 9400148Abstract: A magazine assembly for a firearm in one embodiment includes an outer magazine housing configured for attachment to a firearm and a magazine removably insertable into the housing. The magazine includes an axially extending internal cavity configured to hold a plurality of ammunition shells in stacked end-to-end relationship. In one embodiment, the magazine has an elongated tubular body. A shell catch lever is slideably mounted on the magazine for linear and pivoting movement in one arrangement. The shell catch lever retains a shell in the magazine in a first lateral position and releases the shell from the magazine in a second lateral position. The shell catch lever operates to retain and release shells from the magazine when either removed from or positioned in the magazine housing for loading the firearm.Type: GrantFiled: September 29, 2014Date of Patent: July 26, 2016Inventors: Jason Pittman, Dwight Potter, Scott Warburton

Patent number: 8881444Abstract: A stock bedding system for a firearm is disclosed. In one embodiment, the stock bedding system includes a stock having a pair of bearing surfaces that are configured and arranged to mutually engage a mating pair of bearing surfaces formed on the barrel-receiver assembly. At least one of the four bearing surfaces has a predetermined convex surface profile which causes the barrel-receiver assembly to roll in an angular direction away from one lateral side of the stock towards the opposite lateral side when the barrel-receiver assembly is mounted to the stock. The convex surface profile acts to tighten the engagement between the opposing bearing surfaces of the barrel-receiver assembly and stock providing a secure and vibration resistant mounting. In one embodiment, the convex-shaped bearing surface is defined by a pillar lug mounted in the stock which engages a mating substantially flat bearing surface formed on the barrel-receiver assembly.Type: GrantFiled: December 14, 2012Date of Patent: November 11, 2014Inventors: Scott Warburton, Bruce Rozum, Dwight Potter
