Go to MongKok (旺角) on the Kowloon (九龍) Peninsula. Make your way to Kwong Wa Street (廣華街) and you'll find Hong Kong's airsoft paradise there.
You can find your way to MongKok by the MTR there. There is no need to visit Red Wolf as MongKok pretty much has most of what RedWolf has in stock...
WGC DOES NOT HAVE A WALK-IN STORE. You can order online and have a local pickup, but you're better off not going there.
On Kwong Wa, there's the CA store (very nice), Dentrinity (Overpriced, but lots of parts), Gunners Airsoft (MPEG paradise), Guns N' Guys (Got my Thompson there for very cheap! =) ), and a lot more. You'll be able to get all your gear, guns and almost everything there for a cheap price - even if it isn't around Christmas! And the best thing is, they're almost all by each other.
Take precautions when bringing them over to the US though.
Here's a post I made earlier today about bringing guns over:
How I got it through?
Well, first, I checked the TSA website on their regulations of REAL firearms. And taking precaution, I made SURE that I followed their instructions such as putting them in a hard sided case, unloading it, etc.
After reading all this, I decided to plan out how to make it work. I set out on getting the guns first. I went straight to MongKok and bought my M1A1 and the M4A1. I also asked a few people over there for confirmation on how to get it over here. They told me to remove any trademarks (which I didn't need to) and paint an orange tip on them.
So during my stay, I decided I needed to find a LOCKABLE HARD SIDED case, which I figured I would get cheap in mainland China - which I did.
The day I was about to leave, I took my guns apart to make it more obvious that the guns were fake, and put them in the case.
Upon arrival at the airport, and checking in, we declared that we had "Air Guns" with us. Then security came and called the Hong Kong police. They came with their MP5s and thoroughly inspected the guns. The measured them, took pictures of them and interrogated me.
After that, we were allowed to leave the little room that the guns were being inspected at, and left the case there for the airport to manually place onto the plane. They also placed a inspection sticker on it.
And that's about how I got it over internationally.
I think this is pretty decent for my 1.4K post.
