This is a 20 inch 12 gauge rifled slug barrel with cantilever scope mount from Hastings. Fits Remington 870. This barrel is just about new, was sighted in and that’s it. These barrels are known to be highly accurate. The one I hunt with shoots a single hole at 100yds with its favorite slug. Scope and rings are not included. I have this listed locally. $260 plus shipping. Discreet F&F or postal money order
