I have a 390 30" and a 390 32" step rib barrels. Both are ported and both are very nice and have excellent bluing. 30" is a mobil choked barrel and the 32" is a Seminole package barrel with their own SG2 thread system. Back bored and lengthened forcing cones as well. Let me know if you have interest in either or both. The Seminole 32" barrel has three choke tubes included.
