Remington Factory New. 21" Vent Rib threaded for Rem Chokes so all Rem Choke tubes fit. Chambered for up to 3.5" if used with a Super Magnum receiver but of course accepts 2 3/4" and 3" shells. Comes with an extended Extra Full Turkey Choke .687 restriction. Comes with Ivory Bead sight installed.
This has the barrel ring detent so works with all 12ga 870’s (except tactical models with the 6 shot one piece magazine tube). Yes, it works with Express shotguns as your magazine cap simply pushes the detent down out of the way.
