Mossberg 810 A

Hi ,  I have a Mossberg 810 A for sale . Rifle is in very good condition , with the exception of some markings on the barrel. It appears the previous owner may have clamped it in a vice . Idiot! “ see pics “  Wood is in excellent condition and action is smooth, factory sling mounts as well.  Asking for 500, but open to trades and offers. Would trade for a bolt action 243 or something of an odd calibre.  May even trade for a short canoe, nothing over 14 ft. Local sale only , for now .                          Thanks
