Anna, Marc has first crack at it as he spoke up first, but if it doesnt work out for him (he's shopping for someone else who needs it) then it's yours. I will keep you posted and send a PM and email if Marc doesnt end up needing it. Yes its a 26 vent ribbed, non-ported with 4 choke tubes and tool.
The is a 26" Benelli barrel for the m1 with 4 chokes and tool. i purchased it new 3 yrs ago and shot it only two times (once on the range to pattern on paper, the other whackin ducks). I no longer need the pipe as i have several other scatter guns to shoot at waterfowl with. barrel is in near perfect like new condition as are the choke tubes. Email if interested.
