I contacted the Australian agent for Fabarm who inturn got intouch with the WA agent.
One so called paradox was available 2-3 months ago however when I asked the question about rifleing in both barrels I was informed that one barrel was choked and the other had some rifleing.
Needless to say I passed on it.
The claim was that only one was available in Australia.
The Aussie agents are in Dandenong in Victoria.
