Benefits of technology

The present invention is about a new feature for firearms magazines that allows the shooter to know how many rounds of ammunition are left in the magazine. This is important because many magazines do not provide a way to determine this information, which can make it difficult for the shooter to keep track of their remaining ammunition. The invention includes a sensor that is placed in the firearm magazine and a display screen that shows the remaining number of rounds. This allows the shooter to better manage their ammunition and reload the firearm at a strategic time, improving their overall performance and situational awareness. The invention can be used with a variety of firearms and magazines, not just the AR-15 patterned rifle.

Problems solved by technology

However, many magazines as currently used give no indication of the remaining rounds.

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.

However, many magazines as currently used give no indication of the remaining rounds. The shooter is forced to either keep a mental count of ...
