Michael,
I've got one Mossy 500A with a heat shielded 20" bbl and black synthetic stocks, simple bead up front, improved cylinder choke with a 3" chamber.
It is rugged, solid, smooth enough for my own needs, and sports a simple yet efficient manual of arms.
True, I'd love to get my hands on a set of tac-sighted bbls, plus Tac-Saddle, so on and so forth...
Who knows? Santa's knocking on the door!...
Good luck on your new purchase!
