摘要： A compensated barrel shroud that encloses and supports a firearm barrel provides a first portion of the shroud for receiving the barrel that extends from the firearm frame to an end of the barrel. There is a second larger diameter portion extending from the end of the barrel to a forwardmost outer end of the shroud. A securing nut engages threads at the end of the barrel and secures the barrel shroud to the barrel. An end cap is positioned at the forwardmost end of the shroud. The end cap has an outer hole with an inner diameter substantially equal to an inner of the barrel thereby forming an expansion chamber within the second portion. A plurality of slots are formed along a top surface of the second portion to allow expanding propellant gas from within the second portion to escape out of the slots. These slots are sized and arranged to provide a downward thrust to the barrel shroud to compensate recoil forces generated in firing a round.

摘要： A compensated barrel shroud that encloses and supports a firearm barrel provides a first portion of the shroud for receiving the barrel that extends from the firearm frame to an end of the barrel. There is a second larger inner diameter portion extending from the end of the barrel to a forwardmost outer end of the shroud. The barrel and shroud are screwed together by interengaging threads positioned adjacent the end of the barrel. The end of the shroud has a decreased diameter exit hole defining an expansion chamber within the second larger inner diameter portion. At least one slot is formed along a top surface of the second portion to allow expanding propellant gas from within the second portion to escape. The slot is sized and arranged to provide a downward thrust to the barrel shroud to compensate recoil forces generated in firing a round.
