US 12,760,977 B2 · Adjustable gas regulator valve for direct gas operated firearms

Abstract

An apparatus and methods are provided for a gas regulator valve for adjusting cycle speeds of direct gas impingement operated firearms. The gas regulator valve comprises a gas inlet for receiving expanding gases from a fired cartridge and a gas tube for directing the expanding gases to a bolt carrier comprising a firearm. The gas inlet is disposed at the front of an upper receiver comprising the firearm. The gas tube directs the expanding gases into a carrier key of the bolt carrier. The gas regulator valve includes a plug for controlling gas flow through the gas tube. An actuator disposed on a side of the upper receiver enables operating the plug. The actuator enables a practitioner to adjust the flow of expanding gases without moving the firearm out of a shooting position. The actuator includes a key that may be turned by a rim of an ammunition cartridge.
