From what I gather it is in every way, shape and form, a Mossberg 500, rebranded for WA. Not a clone, a Mossberg 500. Same parts, materials. I paid $150 for mine, first gun I ever owned. For $200 why not. The nice thing is you can configure it however you want or leave it as is and either way you will have a good general purpose shotgun around for not alot of money. I don't know how the older 500's stack up against the Mavericks that can be had for close to the same price, but sounds like a good deal regardless.
I've seen a couple Maverick 88's for sale at my LGS. One with a 20" or 22" bbl with iron sights and another 18" with standard bead. Both new, both $265. I wanted to jump on them but I kind of want a trap gun or a wingmaster if I'm going to buy another shotgun and I don't need 10 shotguns laying around .....
