I examined a Mossy Oak Breakup Remington 870 in a gun shop this morning. It had a Magnum receiver, vent rib 26 or 28 inch barrel with Remchoke, but I could not make out any identification on the opposing side. Is this an Express or Special Purpose? Also, does anybody have experience with the factory camo finishes? Are they durable? Are they paint, powdercoat, or what? Thank you for any assistance.
