Trulock Huglu Precision Hunter 20 Ga Skeet 1. A patent-pending process is used to produce this choke from a block allowing further reduction of recoil with pump-action and its elongated cone is designed to throw tighter and denser patterns than the industry standard. The black-finish reduces light reflection and the matte black finish on the choke tube itself lends to a sleek attractive look.
