Hey all, I am changing out the barrel on the 870 tactical for upland hunting. I bought the 26in vent rib and found out I need that tactical spacer deal because the ring on the barrel that slips over the mag tube is in a different spot. I ordered from Remington but it’s on back order and no date for when there will be more. Has anyone done this mod with PVC pipe or something like that? Tips/tricks? I need to get out and start clay shooting. Thanks!
