well i got a new(old) gun today. picked up an old mossberg 183d-b .410 shotgun. i have always wanted a bolt action shotgun and now i have one. the gun is in decent shape, the barrel will need reblued and im going to refinish and checker the stock. i am currently looking for a modified choke tube for it since it is missing, but i do have the full choke for it. also, is there any way of putting a rear bead on it instead of just having the single front bead?
