20110072958 | FLASH SUPPRESSOR - An improved flash suppressor and silencer mount. The use of tapered tines allows for the easy removal of a noise suppressor from the flash suppressor even after extended use. Due to the construction of the flash suppressor and through proper material selection the tines will not warp or break even after being exposed to temperatures in excess of 1100 degrees. Through the use of angled concave transition portions this device is a superb stand alone flash suppressor. | 03-31-2011 |

20120125184 | FLASH SUPPRESSOR APPARATUS - Flash suppressors having novel expansion features are disclosed. In one embodiment, a suppressor includes an attachment portion adapted to attach to a gun barrel, and a suppressor portion coupled to the attachment portion. The suppressor portion has a suppressor bore that is adapted to be aligned with a longitudinal axis of the gun barrel to allow a projectile from the gun barrel to pass therethrough. The suppressor bore is defined by at least one bore surface having at least one expansion groove disposed therein. The expansion groove may be partially-circumferentially disposed about the suppressor bore, or may include a plurality of expansion grooves. In another embodiment, a flash apparatus includes a suppressor portion having a plurality of longitudinally elongated members spaced apart about a circumference of the suppressor bore, each member being separated from adjacent elongated members by a longitudinal slot, at least one longitudinal slot having non-parallel sidewalls. | 05-24-2012 |
20130025439 | Firearm Blast Shield - An exhaust reflector for cooling and reducing the velocity of firearm, internal combustion engine, and other exhaust gases, and controlling the dispersion of exhaust debris away from the operator. | 01-31-2013 |
20150308774 | Combination Flash Hider and Muzzle Brake - A system and method for a combination flash hider and muzzle brake. The flash hider is upstream of the muzzle brake. This allows the flash hider to take priority over the muzzle brake. The flash hider has slots allowing the exhausting gas to exit, causing the exhaust gases to decrease temperature and pressure to a point below the flash point. This reduces flash. The muzzle brake has at least one port. | 10-29-2015 |
20150308775 | MUZZLE FLASH SUPPRESSOR - A muzzle flash suppressor is disclosed. In accordance with some embodiments, the disclosed flash suppressor includes a plurality of prongs having inner surfaces which taper along their length, providing angled expansion of the primary bore of the flash suppressor in the direction of projectile travel. The inner prong surfaces located along the gas flow path angle outwardly, a multi-radius surface is formed between each pair of neighboring prongs, and chamfers and radii are provided at the prong ends. Some embodiments provide for balanced and gradual gas expansion axially and/or radially along the projectile path, thereby allowing muzzle gases to expand/bleed off in a substantially laminar pattern. In some cases, this reduces secondary ignition of muzzle gases and the ambient air, thereby reducing muzzle flash. Also, some embodiments provide for easy clearance or correction of muzzle obstructions, thereby protecting against damage to the flash suppressor and host weapon. | 10-29-2015 |
20150308776 | METHODS AND APPARATUS FOR FLASH SUPPRESSION - Methods and apparatus for flash suppression according to various aspects of the present technology may comprise a body that is configured to be selectively coupled to a firearm. The body may be formed with curved and or arcing protrusions extending longitudinally along the body. Each protrusion is separated from another protrusion by a gap configured to dissipate gases and unburned materials exiting the barrel of the firearm. | 10-29-2015 |
20150377577 | Harmonically De-Tuned Flash Suppressor for Firearms - A prong-type harmonically de-tuned flash suppressor that is usable with a sound suppressor. As a consequence of its harmonic de-tuning, the flash suppressor does not produce an audible ping when the firearm to which it is attached is discharged, due to harmonic variance among the prongs of the flash suppressor. Harmonic variance, or de-tuning, of the flash suppressor is accomplished by varying centers of gravity of the prongs such that each prong of the flash suppressor has a different fundamental harmonic than each other prong. This harmonic de-tuning of the flash suppressor is accomplished while maintaining each prong at an equal length to each other prong, and while maintaining the general exterior appearance of each prong as being about the same as the general exterior appearance of each other prong. Centers of gravities of the prongs, and thus fundamental harmonics of the prongs, may be varied by placing payloads within the prongs which serve as harmonic dampers. The payloads may be fixed within the prongs, or they may be allowed to freely move within the prongs. | 12-31-2015 |
20160033224 | Flash Suppressing Muzzle Brake - A flash-suppressing muzzle brake for a firearm has a body defining a substantially cylindrical inner chamber and an open front end.

A second flash suppression chamber is defined by the external surface of the conical element, the cylindrical interior surface portion of the body, and the rear portion of the body. Radial openings allow fluid communication of muzzle gases between the first and second flash chambers. | 02-04-2016 |
