Around here you can find it for 250-300 on sale regularly as you spec'd it.

If you want to get it gone ask 230-240 and take a little less if ya have to.

It would be much more attractive with the slug barrel included. Then you might go 300.

But why do you want to sell it - you never really said. Did you buy it just to try out the BP conversion?

You can buy a Mossberg brand fully rifled, ported slug barrel with a 3-9X scope as a package forabout 175 which is factory "laser bore sighted. Mine was dang near dead on as was the one my bud bought for an 870. (Mossberg only makes those combo setups for 500s and 870s as far as I know). That combo sure turned one of my 500s into a real deer killer.
