Mc Millan Barrel 7mm??

[Delta4570]

i have a extra barrell that came with a Mc Millan custom rifle. It is blue and has a muzzel break on it. i have no use for it, the gun had a SS fluted barrel that was allready on it. if i wanted to sell it, could it be used on any other action?? i guess what i am asking are the threads the same on all large actions?

Delta: Just about all actions have a different thread and barrel tennon size. There can also be a enough difference between two actions of the same maker, to cause a problem. As far as fitting another McMillian action, you would just have to try it and see. More than likely it would have to be worked on to index and headspace it, but you could get lucky and only have to screw it on.
