Actually - I just bought one...to put on my Benelli M1 only to discover i needed a different forend - so I bought a M1 barrel instead.
So...I have a barrel that has been installed on my gun but not shot...I have the original box and a choke tube (I will check to see what it is if you are interested). There is a slight mark where the barrel slides into the receiver - like a rub mark - which I put on while installing).
Would you be interested in my M2 barrel (28" matte blue, screw chokes)?
Your gain is my loss @ $450 shipped.
Let me know if you have an interest.
Thanks,
Zack
