TT,
Before you get out the torch and solder make sure you don't have a Poly Choke aluminum rib. If the rib were original it would be machined integral with the barrel. The presence of a Poly on the gun makes me suspicious. The P/C aluminum ribs were held on with a rather flexible two part adhesive and I don't know how effective a re-glue would be. As an alternative you could probably pull the rib all the way off and use the gun sans rib as the original blue is probably intact under the adhesive.
