I'm going to be building a 6.8 SPC using an ARP nitrocarbed 1:10 3r 20" barrel. The barrel is a magnum profile so the size at the muzzle is 0.7"allowing for a threaded muzzle to support a muzzle device or suppressor.

I was originally going to build this on a model 11, but decided to use that action for a 260 Rem build while I was waiting for ARP to get their barrels finished.

Of course right after I made that decision ARP announced the barrels had finally come in.

So I'm thinking that I could build this gun as an Axis fairly economically.

So my question has to do with the size of the various Axis barrels. I would assume that the standard Axis barrels are sporter profiles. Would either of the other two Axis barrels (the SR or HB) be comparable to the magnum profile used by ARP?

To keep the cost of this build down I really would like to be able to reuse everything from the Axis except perhaps the barrel but so the magnum profile barrel needs to fit the factory stock.

Thanks for any insight.
