Mossberg 500 12 gauge

Mossberg 500a pump shotgun. Swapable barrels. 18 or 28 inch. I’ve put 50-60 shells through it since purchased at Cabelas. I’d like to sell both barrels with the shotgun but make me an offer if you just want to purchase one of them. Also note: this is the 500a model, not the 500 so mossberg 500 attachments may or may not fit.
