Abstract
A Recoil, Sound and Flash Suppressor that is machined from a solid metal bar of a diameter determined by weapon caliber and mechanically attached to the end of said weapon's muzzle, with a series of gas ports radially machined to vent gas and create a unique scalloped chamber that is solely held integral by the outer body of said device to sequentially dissipate gas, sound and flash and negate most muzzle movement.
Claims4
A Recoil, Sound, and Flash Suppressor for firearms comprising:
- a generally cylindrical body formed about a longitudinal axis, said body having a first end adapted for connection to a firearm and contained within said body and disposed between said first end and second end defining an axial aperture and a scalloped wall formed by radial geometry of gas ports intersecting the bullet exit port suspended by the outer body wall extending radially outward from said aperture to said body, said wall having at least a portion thereof angularly disposed relative to said axis.
A matched expansion Recoil, Sound, and Flash Suppressor aligned with the forward end of a firearm barrel and bore including:
- (a) a tube having a uniform diameter through bore equal to and coincident with said barrel bore;
- (b) a plurality of outwardly diverging gas ports opening into said through bore forming unique scalloped chambers;
- (c) said gas ports each including suspended chambers adjacent said opening into said through bore;
- (d) the combined entrance area of all of said suspended chambers means having a cross sectional area substantially equal to the cross-sectional area of said through bore so that the mass flow of the propellant gases flowing through said gas ports is substantially matched to that available through said barrel bore.
