If you're alright with playing with transprent airsoft guns, especially when you're just starting out, then you can check these AEGs from ICS and SRC at Wolf Armouries... "If you haven't been able to get yourself registered yet or want to get registered but don't have a gun then getting a transparent gun is a great option. And once you have managed to register you can always get parts to make them black.

We now have the New ICS transparent M4s which have the same split quick change spring gearbox as their normal high grade ICS M4s. Also in stock the SRC upgraded Gen. 2 gearbox G36c and M4A1 in transparent body which offer great reliability and great value for money."
