Designed for law enforcement agencies that want patrol rifles but don't want to use so-called "assault weapons," the Remington 7615 is a unique patrol rifle. Unlike other patrol rifles it's not semi-automatic; it's a pump-action rifle that works pretty much like a Remington 870 shotgun. In fact, the 7615 is kind of like a hybrid of a Model 870 shotgun and an AR-15. This pump-action rifle fires .223 Remington cartridges, and it uses a 10-round low-profile AR-15 magazines. The rifle is available with ghost ring or standard rifle sights.
