I had a 46B find me years ago.
It showed up on my doorstep with a sad story about needing cash.
I gave $50 for the rifle with one 7 round mag, wearing a Bushnell Banner 3x9x40 and a very nice padded leather thumbhole sling.
I have since removed the scope, but still have it, and reinstalled the original style Mossberg peep sights.
It is a tack-driver, and will never be sold by me.
You sure it's a 46B Mgderf? My 46B has a tube mag.
