12 months ago I had to get a b709 to import a stock checkering kit,2 front sights and some fibre optic inserts.
Customs would not release them and the WA Police said it was bullshit on customs part.
Police gave me a B709.

A couple of years ago customs seized a book titled :-Military and police sniper because on page 98 and 99 it had pictures of where to shoot a villan in the head.
The book was seized permanantly.
Another was ordered and came through the system without problems.
This book is also available for sale in Australia.

Go figure !!!!!!!!
