**WARNING** In firearms that use a floating firing pin (such as the AR-15 and its variants), dropping the bolt on a
chambered round could lead to a slam fire. It is important that these firearms are loaded from the magazine so that
the bolt loses inertia when it strips a round from the magazine. It is also important NOT to use sensitive primers that
aren’t designed for use in an AR, as this increases the chance of a slam fire.
