A projectile firing gun or weapon barrel (1) is adapted with a gas porting system (10) having conduits and outlets specifically configured and positioned for maximizing reductions in muzzle jum and recoil. Principles of reverse thrust are maximized to reduce muzzle jum by incorporating porting holes (2) located further rearward than at the barrel muzzle, which porting holes are in fluid communication with gas conduits (12) terminating in upwardly directed openings for maximizing the generation of downward thrust forcest. Venting concentrated explosion gases in a substantially upward direction maximizes downward vector thrust force to counteract muzzle maximizes the duration of thrust forces as gases are vented well prior to the projectile exiting the barrel. The conduits of flow tubes may be configured to function as nozzles (18, 20). The present invention further contemplates varying the internal diameter of the conduit walls to maximize the outlet velocity of gases flowing at subsonic as well as supersonic velocities. |
