Abstract: Systems and methods include implementing a review queue interface that includes: a review queue comprising a listing of distinct review items; a current state for each of distinct review items; a listing for each review item of the distinct review items of one or more client browsers that are interacting with each review item; identifying client browser activity of the one or more client browsers; computing a computed state for each of distinct review items based on the client browser activity; computing changes to the state of review items based on an assessment of the current state and the computed state for each of distinct review items; and automatically updating a state of one or more of the distinct review items within the review queue interface based on a difference between the current state and the computed state of the one or more of the distinct review items.

Abstract: A firearm gas redirection assembly directionally directs discharged gases from a barrel towards a bolt frame, and uses the energy from discharged gases to force a bolt rearwardly in an action. The barrel has an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end. The forward end of barrel forms gas vents. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel and integrates with a bolt frame. The jet nozzle has inner and outer jet sidewalls and a jet nozzle edge. The inner jet sidewall and outer barrel sidewall form a gas space that is in communication with the bolt frame. Discharge of firearm forces high velocity gas through gas vents that form in the barrel, through gas space, and finally against the jet nozzle edge. This forces bolt frame rearwardly.
