Get an injury at work, preferably a bang on the head that could cause amnesia.
Then get a close mucker to pack your MFO box while you are under the weather. Anything else is a bonus.
Stick in another (allegedly) 300 rounds and Bob is your mother's live in lover!
Well IIRC if you are were a civvy on a civil flight there would be no probem so long as you have the relevant cert with you, the firearm travels in the hold and you comply with relevant import restrictions.
I dunno, the mov ops people were kittens compared to RAF PLOD and Cuzzers when certain people used to bring back Dragunov Sporting rifles.
Stick with it Gorilla, if there is a club, there is a way..........or there would'nt be a club. Not quite a gat, but I remember one RAF person who took a hang glider down to Ascension as hand baggage when he went on his tour, should have seen the look on the loadies face when this guy and a couple of mates start hoiking the glider up the ramp on the Herc.
I know sweet FA about guns regulations but break the issue down into three parts:
1. Taking your guns out of UK (and bringing them back again)
Presumably your licencing authority are the contact point for advice. Find out whether you have to declare SORN or whatever.
2. Transporting your guns
Contact RAF movements at Brize.
3. Importing your guns into FI (and getting them out again) and use in FI.
Contact the FI Government. Their UK phone number is +44 (0)20 7222 2542. It'll be cheaper than using the +500 number. When you think you have the answers, e-mail the Government in Stanley just to make sure that both offices are giving the same advice. firstname.lastname@example.org
Then post the results of the three lines of query on ARRSE. I doubt that you'll be the only/last user to have the same plans.
There's another one...
4. When you've got these answers, find out about gun storage at MPC (RIC? RAF?) and/or the Club.
