Hastings 12 gauge rifled slug bbl, 2 3/4 or 3 inch, 24 inches long, 1-34 twist, with cantilever scope mount, special paradox rifle bore.
These barrels are known for excellent accuracy. I'm just clearing out some stuff that I don't use. Again, this is a brand new barrel for a Remington 870.
Bought barrel & Installed A Nikon 3-9x40 Slug Hunter scope & never shot it. $450 shipped to your door
