AUG a2
 

ok this is kinda a stupid question, but I need a new inner/outer barrel for my AUG a2 Carbine I want it to be the stock full length. So the inner barrel has to be 510mm ish. Where can I find this with out over paying?

other option is ether a A3 set or a phontom kit

what do you mean overpaying? those parts are not restricted. You can order them from any website and pay the price listed without having to worry about them being confiscated at the boarder. I recommend to order from Redwolf Airsoft. As for the inner barrel, get a Prometheus one. You will really love the accuracy.

I like the inner barrels i saw but I am still unsure on what i should get as a R.I.S system and outer barrel that will fit a 510mm inner barrel.

The stock AUG barrel IS 510mm.

I already knew that.. my AUG came with a 365mm carbine setup when I got it( I bought it from the classifieds) so now i have to get parts to make it an assault rifle again
