    Neat video.

    FYI, If anyone tries this I urge them to gauge out the firing pin protrusion. Too much protrusion can pierce the primer and blow the gun. They also need to be sure the firing pin does not bind in the bolt or on the FPRP as it can allow a slam fire.

    Might be a good idea in an emergency but since the steel in most nails is very low in carbon content, it cannot be hardened and will not last very long.

    Wouldn't that be like firing from the open bolt position and fire a whole mag with one pull of the trigger?

    If the firing pin binds and there is sufficient Protrusion yes. Very dangerous on a gun with a locking mechanism too.

    wouldn't a protruding firing pin prevent the cartridge from slide up into feeding position?

    No, the AR forces the rim over the extractor when going into battery. If the firing pin is sticking out too far it will either cause the primer to go off and slam fire, or it will just dent the primer.

    I thought that could have been it but couldn't swear to it. Thanks for the learning.
