Wanted Barrel's NEF handi rifle

[MaverickOFW]

G'day , I am chasing some barrels for my N.E.F single shot Handi rifle.
I allready have the SB1 12 gauge barrel as well as the sb2 45/70 cal, if anyone is out to unload any other cals I would be interested.

I am in Perth Western Australia so pick up would be a little difficult, so if you don't mind sending it thru the mail or using a courier it would be appreciated.
I'm after a .270 or .308 or a small cal like a .222 or .223

Even a link to a shop or online store that has them would be good, importing a barrel is ok , it's only actions that need a lic here in WA.

THANKS , Brendan.
