Tommy1957, per an internet forum, "The Roadblocker apparently did have a vent rib option for $34 extra bucks back in 1984-85. An "RB" is shown with plain, and ribbed, barrel in the write up "Fighting Shotguns" in the 1985 Guns Illustrated, as well as in the back catalog description."
The barrel is 21"-22" and has a parkerized finish. The stock is stock is plain with no checkering. The forearm has checkering. See pictures. As you can tell from the pictures, the wood on this gun is really nice.
