Abstract: A firearm attachment may include a threaded adapter, and the threaded adapter may include a first threaded portion and a second threaded portion. The second threaded portion may include an inner threaded portion and an outer threaded portion. The firearm attachment may include a housing that may be configured to couple to the outer threaded portion. The firearm adapter may include a reverse baffle compensator that may be configured to couple to the inner threaded portion. The reverse baffle component may include a first baffle portion and a second baffle portion, and a channel may be disposed between a first narrow end of the first baffle portion and a second narrow end of the second baffle portion. The reverse baffle portion may include one or more holes on a sloped portion of the first baffle portion and one or more holes on a sloped portion of the second baffle portion.

Abstract: A round counter for a firearm is provided that includes a display that provides the user with information regarding the number of rounds remaining in the magazine of the firearm. The magazine includes a round follower and a wiper extending from the follower. The wiper contacts a variable resistance sensor, such as a linear potentiometer, that is attached to a sidewall of the magazine. As the round follower and wiper move up and down within the magazine, the wiper contacts the sensor at different positions. The position of the wiper relative to the sensor corresponds to a specific linear distance indicative of the number of rounds remaining in the magazine. Information regarding this position, and consequently the number of remaining rounds is transmitted to the display.
