Wanted: CZ 455/457 .22 barrel

Hi , I want a bit heavier barrel for my rifle.  Looking for 16-20", would like like thread muzzle as well.

I currently have a matching serial number super-match which shoots really well, but for the type of shooting I am presently doing, a heavier barrel should suit my needs much better.

The supermatch  barrel is available for trade.  No sights; these were missing since I bought it.  I have included a picture of my rifle with the Supermatch on it.

Thanks,

Mark
