US Patent 11204213 Firearm magazine loader

The present disclosure provides a firearm magazine loader. The firearm magazine loader includes an outer sleeve and an inner sleeve. The outer sleeve is movably connected with the inner sleeve. An inner surface of an inner side wall of the top opening of the inner sleeve is a non-slip surface. The non-slip surface prevents the guiding mechanism from bringing out bullet loaded in the interior of the inner sleeve when the inner sleeve is pushing out.
