All barrels are ported the same. Fixed chokes. O/U is top/.031, bottom .027. Top single barrel is .031. Bolt was just redone, and locks up tight. Stock has some remnants of glue from a comb addition of some type of cloth, or pad. Otherwise the wood is in good shape with no cracks. The metal is in good shape, except for the typical forearm metal crack, (Pictured). Comes with original case. $1075 shipped. Please pm with questions. Thanks, Jon.
