Publication number: 20140345444Abstract: A Picatinny mounted, left side charging handle system adapted for mounting on AR-15, M-4, or M-16 and similar rifles. The charging handle mounts on the foremost Picatinny mount of the upper receiver and replaces OEM charging handles provided with the rifle. Side mounting overcomes the problem of a shooter's finger being moved from the trigger and/or the shooter's cheek moving from the stock weld so that the shooter's eyes may remain on the intended target. The novel charging handle mounts on the upper receiver and readily accommodates mounting virtually any optical device in addition to the charging handle. The novel charging handle may be mounted to the rifle with no rifle modification required. Rifles may alternately be charged by pulling back a protruding rear portion of the charging handle. The apparatus may readily be transferred between rifles. The rifle equipped with novel charging handle remains fully field strippable without tools.Type: ApplicationFiled: August 4, 2014Publication date: November 27, 2014Inventor: Camaron Randolph Hillman

Patent number: 8297164Abstract: A remotely operable machine gun charger is provided for selectively controlling the forward-to-rear movement of a machine gun bolt pin. When the bolt pin is released from its safe position the charger permits the bolt pin to be spring-driven back to its armed position substantially instantaneously by the bolt spring without waiting for pin engagement and drive structure portions of the gun to be returned to their forwardmost positions. The charger permits the gun to be fired during such movement of the engagement and drive structure back to their forwardmost positions, and the charger may be mounted on and removed from the machine gun without the use of tools, or the necessity of removing or adjusting any of the internal components of the machine gun.Type: GrantFiled: May 19, 2011Date of Patent: October 30, 2012Assignee: Contract Fabrication and Design, LLCInventor: Russell D.

Publication number: 20120260791Abstract: The invention relates to improvements in the design and operating mechanisms in a KRISS-type firearm, or a firearm employing a mobile mass. In one aspect, the invention is an improved cocking lever assembly comprising a main pin provided with a tenon (9) at one end (E), with a supporting compression spring (5), a cocking button (3), and a retention means (4), attached to a mobile mass (1). This assembly allows direct activation of the mobile mass (1) by the action of the operator's force on the cocking lever. Advantageously, this cocking lever assembly can be mounted indiscriminately on the right or the left of the mobile mass (1) and therefore of the firearm, according to the user's preference. This cocking lever assembly combines certain safety criteria with the option of ambidextrous use often preferred in modern firearms.Type: ApplicationFiled: December 12, 2011Publication date: October 18, 2012Inventors: Renaud Kerbrat, Antoine Robert, Jan Henrik Jebsen

Patent number: 8266998Abstract: A kit, system and method for modifying an AK-variant firearm to permit bolt carrier pull back by the right or left hand. The kit, system and method includes a receiver cover including an arch-shaped crown and a pair of opposing retaining fins affixed to the bottom of the crown. One retaining fin has a slot that extends along the length of its upper portion. A guide track is affixed to the retaining fin having the slot. A charging handle assembly is secured to the guide track and is slidably engaged with retaining flanges and adapted to move along the guide track. An auxiliary charging handle is affixed to, and projects from, the slide. An engagement pin affixed to the slide projects inwardly to extend through the slot to engage the bolt carrier and move it when the charging handle is pulled.Type: GrantFiled: February 16, 2012Date of Patent: September 18, 2012Inventor: Doug Davis

Patent number: 8261650Abstract: The invention concerns a cocking device for a bolt mechanism with a cocking slider (13, 14), which can be displaced, on a breech housing (2), between a rear uncocking position and a front cocking position, for the cocking and uncocking of a striker spring and a catch (21), located on the cocking slider (13, 14), which works together with a mating catch (23) to hold the cocking slider (13, 14) in the front cocking position. In order to attain an improved safety with respect to an unintended release of a shot, an uncocking mechanism (25, 29) for the automatic uncocking of the striker spring (48), when the magazine (5) has been removed, is correlated with the cocking slider (13, 14).Type: GrantFiled: December 6, 2010Date of Patent: September 11, 2012Assignee: Blaser Finanzholding GmbHInventors: Oliver Hagspiel, Peter Wiedemann

Patent number: 8161861Abstract: The present invention is a battery assist devise to aid in the locking and unlocking of the bolt in a long firearm. The battery assist devise attaches to the both catch button of the firearm and thereafter acts as an extension thereof. The battery assist device comprises an interface head and attachment plate, which secure about the bolt catch button, and a curved lever that protrudes from the head and projects around the underside of the firearm, through the trigger guard area, until it projects slightly on the opposite side of the firearm. The lever then is capable of ambidextrous operation.Type: GrantFiled: August 12, 2009Date of Patent: April 24, 2012Assignee: Magpul Industries Corp.Inventors: Travis D. Haley, Eric C. Burt

Patent number: 8156854Abstract: A firearm includes a receiver and a bolt carrier disposed in the receiver. The bolt carrier is moveable between a firing position and a rearward position. A rod is fixed relative to the bolt carrier and a hand guard is coupled to the receiver about the rod. A handle assembly is slideably supported by the hand guard and is moveable toward the receiver to define a charging motion and away from the receiver to define a forward assist motion. The handle assembly receives the rod during both of the charging and forward assist motions. An arm is coupled to the base and is moveable between a disengaged position spaced from the rod and an engaged position abutting the rod. When the arm is in the engaged position, the handle assembly is moved to move the rod and the bolt carrier in either of the charging and the forward assist motions.Type: GrantFiled: July 1, 2009Date of Patent: April 17, 2012Assignee: Adcor Industries, Inc.Inventor: Michael J. Brown

Publication number: 20120042769Abstract: A non-reciprocating, self-engaging charging handle is disclosed. It comprises a spring biased forward latch mounted upon a sliding body with a protruding handle. The spring bias causes the latch to positively engage the firearm's bolt carrier group when the handle is brought forward into contact therewith. A secondary latching system secures the charging handle to the upper receiver when not in use and disengages automatically when and only when a user desires to operate the handle.Type: ApplicationFiled: January 19, 2011Publication date: February 23, 2012Inventors: Brian L.
