A rare Mossberg 500A ?

[45/70fan]

I found the last of dad's guns stashed in a closet while cleaning out the house and I can find nothing online about. The s/n dates it to 1997 I believe. The odd part... it's got an 18.5" Accu-Choke barrel with a screw in fiber optic bead and no vent rib. The barrel is stamped Accu-Choke so I know it's a factory barrel. The barrel appears to be thicker than a standard barrel. There is ZERO info, listings, etc online on this barrel that I can find. Also found a 28" Accu-Choke barrel hidden away. Any info would be appreciated.

Thanks, you found more than I did. I'll see about adding more pics tonight. That ebay description sure sounds like it. Sounds like I have what's becoming a unicorn...
