I have ordered several bits and pieces from them over the last 12 months the last was 2 sets of rings from them and have had no dramas what so ever with sending them. My last order was here in 8 days using us express postage/insurance. The online ordering is very secure and if you were to call them (Midnight our time here)they are very friendly will take your order over the phone and tell you the exact costs posted, plus they also have some very knowledgeable fellas willing to help with advice if your not to sure about something.
Unlike Midway, Brownells will post gear to Australia
