Stevens Model 87B, .22 short, long or long rifle cal. semi-auto rifle. NSN. Good condition, but missing the feed tube - dovetail is under the barrel. 24" barrel has an excellent bore. Bluing is 95% and nice. Tight action. Stock has some marks, but rates as very good. Needs some parts to rise again! Could be used as single shot... That is NOT a magazine well at the bottom. Don't know what the "lever" is. Looks like hillbilly engineering. Selling as parts only. C&R OK. Gunrunner West item.
