Abstract
A shock reduction muzzle brakefor the muzzle end of a gun barrel(i) maintains sufficient rearward-facing surface area in the path of the expanding propellant gas to counter the recoil, while also (ii) guiding shock waves away from a path of a projectileand (iii) decreasing the rate of base decompression to minimize decompression shock. The muzzle brakeincludes (a) a tubethat defines a path for a projectile, and (b) multiple forwardly-inclined holesextending through the side wallof the tubeto divert propellant gases away from the path of the projectile. The forwardly-inclined holeshave an outlet of that is closer to the forward endof the tubethan the inlet of the hole, thereby limiting the surface area that could reflect shock waves back onto the projectile. The holesare sized to slow release of the base pressure to minimize decompression shock.
