Abstract: A sound suppressor for a firearm has one or more stacked baffles surrounded by an outer sleeve positioned such that an air gap exists between the baffles and the sleeve. The sleeve is connected to an outer portion of each of front and rear caps. The baffles are connected between the front and rear caps. The outer portions of the front and rear caps are disproportionately ventilated to induce directional air flow so as to facilitate heat dissipation.

Abstract: A magazine assembly (10) for receiving and storing cartridges (28) for a firearm (1). At least one gate member (58, 60) is pivotally mounted at an open end of a monoblock (20) and has a first blocking member (58.1, 60.1) to inhibit feeding of an end cartridge from a feed port until the firearm (1) is cocked. The gate member (58, 60) further includes a second blocking member (58.4, 60.4) to prevent multiple cartridges (28) from feeding from the same feed port (20.3, 20.4) during a given cocking cycle. The gate member (58, 60) is operable to displace the first blocking member (58.1, 60.1) out of a cartridge feed path while placing a second blocking member (58.4, 60.4) in the feed path to of the next cartridge (28) to be fed. An interrupter (62) prevents cartridges (28) supplied by a plurality of feed ports (20.3, 20.4) from being fed simultaneously.
