AR and Tactical style rifles have a handful of different uses. Home defense, predator hunting, punching targets, or even for competing in shooting competitions. Owning an AR style rifle is a right for American citizens. As a firearm owner, it is your duty to perform cleaning and maintenance to ensure the protection of your investment. To help ease this process, Remington offers a cleaning kit designed to help AR shooters carry out that duty. Brass rods and components feature Mil-spec 8-32 threads.
