Abstract: 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.

Abstract: A maintenance kit incorporated into operable components of a sub caliber action device installable within an upper receiver of an AR-15 type firearm for facilitating disassembly, maintenance and reassembly of a bolt and forward chamber adaptor with a receiver plate. The kit includes at least one gauge dimension defined in a barrel of the forward chamber adaptor for establishing a correct spacing between lengthwise extending and interior notch defining arms associated with the receiver plate. A modified guide rod facilitates at least one of disassembly of the bolt firing pin/extractor and cleaning of the chamber adaptor interior prior to reassembly of the bolt and chamber adaptor.

Abstract: A retrofit chamber adaptor associated with a substitute action assembly incorporated into a firearm for permitting the substitution of an original designated cartridge for a substitute cartridge. An elongated body is incorporated into a barrel accessible location of the firearm and supporting a bolt in reciprocating fashion. The chamber adaptor is mounted to forward end of the body in communication with the reciprocating bolt and exhibits a modified diameter aperture extending therethrough and corresponding to an incremental modification in diameter associated with the substitute cartridge. Additional features include a receiver plate incorporated into the body and exhibiting a generally lengthwise extending notched or keyed interior established between generally parallel extending sides with identified and interiorly notched locations for seating in reciprocating fashion therebetween the reciprocating bolt. A further variation of the adaptor exhibits a dual rail configuration to which is reciprocally mounted the bolt and from which in turn forwardly projects a firing pin. In a preferred application, the chamber adaptor permits substitution of a 0.22 LR rimfire cartridge in lieu of a normally designated 5.7×28 mm center fire cartridge.

Abstract: A modularized upper receiver including any number of replaceable panels applied to either the left or right side of the receiver for establishing varying combinations of forward assist and spent shell/gas deflection. The modifiable upper receiver is particularly suited to ambidextrous use and, in the further instance of forward assist notches added to an opposite side of the carrier, prevents the shooter from removing such as the right hand from the pistol grip in order to force feed rounds into the firing chamber.

Abstract: An anti-rotation feature incorporated between a cotter pin and a sub caliber action device installable within an upper receiver of a firearm. A receiver plate exhibits a notched interior for seating a bolt in reciprocating fashion. A chamfer formed in a side of the bolt intersects a length extending channel of the bolt for seating within the notched interior. The chamfer seating a head of the cotter pin to prevent rotation during bolt travel. A rearward support sleeve seats an opposing guide rod associated with the receiver plate and in order to maintain the bolt assembly. A firing pin exhibits a notch at a location along its shaft and, upon installation within an interior aperture of the bolt, is retained in position by the cotter pin. The firing pin is configured so as to exhibit a reduced diameter end projection upon which is supported a coil spring.

Abstract: A bolt catch assembly configured for operating with rimfire ammunition for use with a firearm including a receiver with an exposed receiving chamber. The assembly includes a bolt catch actuator housing supported in seating fashion relative to the receiving chamber and communicating with an attachable magazine. A catch actuator is supported in elevatable fashion relative to an end of the actuator housing. A bolt catch component and integrally formed actuator catch engaging portion is slaved to the catch actuator in order to be displaced in response to elevating motion exerted upon the catch actuator, such as by a follower component biasingly disposed within the magazine. The follower, in its uppermost displaced position within the attached magazine, engages a tab associated with the catch actuator which extends over a communicating interior of the bolt catch actuator housing in communicating alignment with the exposed receiving chamber. An end configured location of the bolt catch housing includes a step and ledge profile for supporting an underside of the catch actuator in each of a seated rest position as well as a follower induced and upwardly displaced position.

Abstract: A combination magazine and outer skin for a firearm including a magazine core adapted to releasably engage a firearm in communication with an action assembly associated with the firearm. Multiple cores are stackable end-to-end to define a continuous interior, with an end cap engaging an open bottom of a lowermost core. A design indicia exhibits an interior recess and is assembled around the stacked cores. A dual use follower is in use with an uppermost located magazine and maintains the assembly bolt in an open position and following the last cartridge being fired until such time as the magazine is removed. In the further variant, with a BHOA installed in place, the follower activates the BHOA and the bolt to remain in the retracted/open position, following magazine removal.
