Systems and methods for an adjustable gas block are described. Systems may include an adjustment subassembly. The adjustment subassembly may include a valve stem end with a front-most portion larger in diameter than the rear-most portion and a boss extending from the forward portion of the valve stem end; a valve ring surrounding the boss of the valve stem end; a valve threaded portion for receiving the boss of the valve stem end and having a threaded portion; and a valve rotator coupled to the valve threaded portion for adjusting the flow of gas. Systems may include a gas block assembly. The gas block assembly may include a gas block through hole; a first duct to direct pressurized gas from a barrel to a plenum; a second duct to direct a regulated volume of gas to a gas operating system; a seat valve to control the regulated volume of gas to the gas operating system; and a gas block threaded portion for coupling to the valve threaded portion. The adjustment subassembly may be coupled to the gas block assembly.

A bolt carrier for use with the AR15/M16 family of firearms is provided. The bolt carrier includes an integrally formed carrier key and spherical strike face surrounded by a cylindrical counterbore made with a downward angle to act against the tilting force imparted by the operating rod of the firearm's gas operating system. The outer surface of the carrier includes upper and lower running rails that all extend fully to the front face of the carrier to lengthen the carrier's rail support or bearing surfaces against the receiver. To improve the robust operation of the firearm in over the beach operations, the bottom and rear of the receiver extension has drain holes formed through which water is forced out of the receiver extension by the reciprocating action of the bolt carrier when the weapon is fired.

Self loading firearm bolt carrier with integral carrier key and angled strike face

An automatic rifle bolt carrier with a fluted boss for the AR15/M16 family of firearms has been provided. The rear of the bolt carrier has been provided with a boss having bearing surfaces which are in operational contact with the interior of the host firearm's upper receiver to prevent the carrier from tilting while it is reciprocating during normal operation. The boss and rearward end of the bolt carrier are provided with flutes which allow water to flow between the buffer tube and upper receiver while the bolt carrier is reciprocating during normal operation, enabling a properly equipped firearm to be used during over the beach operations. The bolt carrier also includes a scallop cut located about the top of its backmost end which is perpendicular to the longitudinal axis of the bolt carrier.

A support structure for establishing a computer workstation around a chair, such as an easy chair or wheelchair. The support structure includes a flat base having a plurality of vertical posts projecting upwardly therefrom. Two of the posts have swing arms terminating in additional swing arms. An inclinably adjustable support platform is disposed above each final swing arm. Either support arm may optionally have a drawer and a clip for retaining papers. The compound swing arms enable the platform to be adjusted to any desired proximity to the post, within a range. The working surfaces of each support platform can be inclined, and the height of each support platform can be adjusted. The support structure has optional auxiliary features including a cup holder, a pencil tray, storage shelves and a filing cabinet, a tabletop having a drawer and a cover panel depending therefrom, for concealing power and communication cables, power cables disposed within the posts, a power supply, an exposed power jack connected to said second power cable, and an auxiliary support for supporting a speaker thereatop. One alternative embodiment includes a motor and a mechanical linkage for adjusting swing arm position.
