The present invention relates to a silencer for reducing muzzle blast and noise of firearms or similar devices. The present silencer has a hollow cylindrical or other shape casing comprising front and rear end caps and an opening aligned along a longitudinal axis defining a passage for a projectile and propellant gases to emerge from the muzzle opening. A plurality of serially placed baffles of symmetrical or slanted orientation and intervening coaxial spacers are positioned within the casing and define a multitude of chambers among the baffles, spacers, and outer housing. The baffles shear propellant gases away from the projectile path and through openings or ports into additional chambers formed between the spacers and outer housing. The arrangement of baffles and spacers provides flow-impeding paths, dispersion, and controlled expansion of gases and lowers gas temperature to reduce audible noise and observable signature of the muzzle blast.

The invention claimed is: 1. A silencer for a firearm comprising: a casing having an axis and including: a rear end having an entrance opening, and a front end having an exit opening, each opening defining a path for a projectile; a plurality of baffles disposed within the casing and each having an aperture therethrough, at least one of the baffles being an oblong baffle and slanted at an angle with respect to the axis of the casing such that a first end of the oblong baffle is disposed closer to the rear end than the aperture with respect to the axis of the casing and a second end of the oblong baffle is disposed closer to the front end than the aperture with respect to the axis of the casing; and at least one spacer extending from the oblong baffle to an adjacent baffle of the plurality of baffles, the spacer comprising at least one planar wall having two sides, each side being flush with the casing such that a chamber is defined between the planar wall and the casing and a projectile passage is formed opposite the chamber. 2. The silencer of claim 1, wherein the spacer is formed as a polygonal tube comprising a plurality of corners, each of the corners contacting the casing. 3. The silencer of claim 1, wherein the spacer includes at least one cut-out forming an opening between the projectile passage and the chamber. 4. The silencer of claim 1, wherein the chamber is bordered by at least the oblong baffle. 5. The silencer of claim 4, wherein the oblong baffle bordering the chamber includes a cut-out therein adjacent the chamber. 6. The silencer of claim 1, wherein at least one of the baffles has at least one of a raised section or a recessed section. 7. The silencer of claim 1, wherein at least one baffle has an arch shape such that it is either concave with respect to the front end, convex with respect to the front end, or curved in an S-shape. 8. The silencer of claim 1, wherein the baffle nearest the rear end of the casing is a blast baffle, the blast baffle having a different angle with respect to the axis of the casing than the angle of one or more of the plurality of baffles. 9. The silencer of claim 8, wherein the shape of the blast baffle is selected from cone shaped and primarily flat. 10. The silencer of claim 8, wherein the shape of the blast baffle is generally symmetrical. 11. The silencer of claim 1, wherein at least one of the plurality of baffles and the at least one spacer is a single piece. 12. The silencer of claim 1, wherein the oblong baffle is slanted at a first angle with respect to the axis of the casing, wherein another of the plurality of baffles is slanted at a second angle with respect to the axis of the casing, and wherein the first angle is different than the second angle. 13. A silencer for a firearm comprising: a casing including: a rear end having an entrance opening, and a front end having an exit opening, each opening defining a path for a projectile; a plurality of baffles disposed within the casing and each having an aperture therethrough, at least one of the baffles being a planar oblong baffle slanted at an angle with respect to an axis of the casing and having at least a portion that is flush with the casing; and at least one spacer disposed within the casing adjacent the planar oblong baffle, the at least one spacer comprising at least one planar wall having two sides, each side being flush with the casing such that a chamber is defined between the planar wall and the casing and a projectile passage is formed opposite the chamber. 14. A silencer for a firearm comprising: a casing having an axis and including: a rear end having an entrance opening, and a front end having an exit opening, each opening defining a path for a projectile; a first oblong baffle disposed within the casing, having an aperture therethrough, and being slanted at a first angle with respect to the axis of the casing such that a first end of the first oblong baffle is disposed closer to the rear end than the aperture with respect to the axis of the casing and a second end of the first oblong baffle is disposed closer to the front end than the aperture with respect to the axis of the casing; a second oblong baffle disposed within the casing, having an aperture therethrough, and being slanted at a second angle with respect to the axis of the casing such that a first end of the second oblong baffle is disposed closer to the rear end than the aperture with respect to the axis of the casing and a second end of the second oblong baffle is disposed closer to the front end than the aperture with respect to the axis of the casing, the second oblong baffle being slanted in substantially the same direction as the first oblong baffle; and at least one spacer extending from the first oblong baffle to the second oblong baffle and comprising at least one wall having two sides adjacent the casing such that a chamber is defined between the wall and the casing and a projectile passage is formed opposite the chamber. 15. The silencer of claim 14 wherein the first oblong baffle, second oblong baffle and at least one spacer are a single piece.
