Abstract: Embodiments described herein relate to suppressors for reducing or eliminating sound, flash, and/or heat generated by firearms while discharging projectiles. The suppressor includes a unitary structure containing a cone shaped nozzle disposed at one end of a body. The body has a plurality of baffles surrounding a central bore, a breech end opposite a faceplate, and a plurality of cooling channels spanning a length of the body. Each cooling channel has a first opening at the breech end and a second opening at the faceplate. The unitary structure further contains an outer ring spanning from the breech end to at least the faceplate, a longitudinal wall spanning from the breech end to the faceplate, and a plurality of radially oriented walls extending between the longitudinal wall and the outer ring. The plurality of cooling channels is disposed between the longitudinal wall, the outer ring, and the radially oriented walls.

Abstract: A slideable ejection port cover having at least two configurations, an open configuration in which shell ejection via the ejection port is enabled, and a closed configuration in which the ejection port is substantially immovably covered; the ejection port cover comprising a shutter operatively connected to a locking component, the shutter slideable along a longitudinal axis of the receiver; wherein the locking component comprises a spring configured, at such times as the ejection port cover is in the closed configuration, to hold the locking component in a pressure-applying mode against the receiver, the pressure-applying mode being a default mode, thereby immobilizing the shutter relative to the receiver, and the locking component configured to compress the spring when pulled manually away from the receiver, thereby enabling reversible transformation of the ejection port cover from the closed configuration to the open configuration.

Abstract: A modifiable piece of jewelry has at least two ornamental display components. The first display component has opposite front and back sides which are finished as jeweled, gemstone, precious metal exterior or other finished ornamental display surface. The display surfaces are different and, in most cases, contrasting in ornamentation, color, jewelry setting, gemstone design, or precious metal exterior surface. A second ornamental display component also has opposite front and back sides with jeweled, gemstone, precious metal exterior or other finished ornamental display surfaces. The second ornamental component fits snugly within a cut-out of the first ornamental component. Internal surfaces of the first component and external surfaces of the second component form tight surfaces-to-surfaces connections, in order to maintain the components one within another.
