I have a factory 870 18.5" cylinder bore HD barrel that was taken off of my Express when i SBSed it. I only fired it enough to funtion test the 870 before sending in the paper work for the tax stamp. It probably has 20 rounds through it. It does have a few handling marks that it came with from the factory. Other than that it is in excellent condition. I will take $100 plus shipping in the lower 48. First I will take it in the tread gets it. Payment PP or MO.
