Remington Factory Bead. This is the perfect replacement bead for your steel bead if it is threaded. Pedestal beads are pressed in so this will only work on Vent Rib Barrels. You simply screw the steel bead out and screw this one in. This is part F202850 on the 2020 Remington parts list and retails for $8.99.
Yes, fits all 870 Vent Rib Barrels. So if you buy any of the Vent Rib barrel here on the store and puchase this I will install it for you for free. Let's see the big boy web stores do that for you.
NOTE: when installing do not grip bead with pliers as you damge it. Grip the base of the bead. You can screw in by hand and then tighten by using small pliers on the base of the bead.
