Norinco HP9 Remington 870 clone "defender" 20-inch barrel 7+1 magazine

Hi folks, here's a fun gun. Built on a very robust Norinco HP9 receiver (actual clone of the Rem 870), with Remington laminate stock, a Choate magazine extension (7 in the mag tube +1 in the chamber), an ATI heat shield. The barrel was shortened to 20 inches (Remington barrel, for 2 3/4" shells) and a bead installed. Feeds and ejects well (tested with dummy rounds, see video). Feel free to ask any question. $600 plus shipping, local pickup is ok. PAL will be verified of course. No trades.
