    Since there are no aftermarket barrels for the Marlin 60. Can the factory barrel be modified to achieve a bentz chamber? If so what exactly needs to be done and who should I send it to?

    I am not a gunsmith, but I think you would have to cut it off at the breech end, turn a new shank to fit the action, and rechamber with the Benz reamer. Then worry about the tube magazine hangers.

    You might ask on RimfireCentral.com

    It can be done by setting the barrel back past the original chamber and re-chambering it.

    I believe the Model 60 uses a pinned-in barrel with a slip-fit barrel/receiver joint. That is, it is not threaded to the receiver, or clamped in with bolts like the Ruger 10/22.

    As such, it is doubtful you would gain much in the way of accuracy by setting the barrel back, re-chambering it, re-cutting the extractor clearance slots, etc.

    When you get done spending big bucks to do it, you will have a Bentz chamber on a loose barrel/receiver joint.

    You would probably be money ahead, and get as good accuracy, by spending the money on Match-Grade ammo your rifle shoots well as is.
