NOW LEGAL FOR WASHINGTON STATE RESIDENTS!!!These are factory built by Remington Arms, not some chopped-down used 870 built in a guys garage that happens to have his Class 2 manufacturers license! This is known as the breacher model, a highly modified 870 AOW that is made to blow the hinges and locks off of doors for dynamic entries in regards to law enforcement and military use. Special 10" barrel(can't be put on standard 870), modified magazine tube and fore end. This is all done by Remington which makes it very collectable and rare. 3" mag chamber with MAGNUM marked receiver. Comes as shown in picture.
