m2 18.5" barrel: where to purchase?

[ccoker]

I have an M2 28" field for bird hunting, would like to get a 18.5" barrel for one, any pointers on where to find a good deal?

Try Gunbroker.com?

I have looked from time to time..
looking for maybe a dealer recommendation that perhaps knows "hey, call Bill at XXX, he usually has one or two at a good price" :)
