Wanted: Cz 457 MTR barrel Wanted

Looking for an 18" cz 457 MTR barrel for sale. Located in NB but willing to pay for shipping. 

I'm hoping someone may have upgraded to a custom barrel and may still have an MTR barrel laying around. 

I also would be willing to trade my current barrel towards this if you are interested. Currently running the 16.5" varmint barrel, plenty accurate, just looking to step up to the match chamber and gain a little bit of length.
