When I had to switch for RH to LH long guns one of the first things I bought was a LH Wingmaster. The rib was off centered, so back to the factory it went and was repaired/replaced. I bought a couple of extra barrels for it over the years, but had the original barrel cut shorter and PolyChoked. It has been a sweet shooting shotgun for me, not that I'm much of a shotgunner. I wish I'd picked up a LH slug barrel for it. Maybe the new folks will produce a batch.
Remington got sued over the metal in their 870 barrels. They recalled some and offered some kind of deal to owners to resolve the issue. Some barrels were sold pretty cheap rather than go through the red tape.
