I have a Bintac B&W M50 for sale (.495 caliber) for $600 shipping included. I have only shot this gun once where I put about about 50 rounds through it. Seems to work fine. I need to part with it to pay some bills with Christmas season coming around. Nothing wrong with it. I have the original box and it is still under warranty with Bintac LLC. Scope not included. I also have about 50 rounds of Mr. Hollowpoint .495 caliber slugs I'll throw in with the deal. Comes with two 6-round mags and a fill probe. I will ship with a tracking number to you.
