I've already answered his question. He asked what are the sizes of 1/6 scale guns, and give em' the appropriate answer: a direct link to the 12" action figure thread, since guns used on those kinds of figures are in 1/6. What have I done to cause so much trouble anyway? Geez, some people really need to have their funny bone adjusted.
Ah, of course, Thailand: where everything illegal elsewhere is always legal there. You can get springer airsoft there far cheaper than having lunch in KFC. Heck, make that twice cheaper if you could spot a bargain!
That AK of yours is of CYMA yes? Anyway, a contact from the Internet told me that it's also easy to get those things in Sarawak (that's where you're from, yes?), at a lesser price than those in the Peninsula.
I heard RC airsoft tanks are legal. Saw em' being sold in Lelong.com.my. Try searching there and you might also stumble across cheap airsoft BBs. they're 6mm low-quality Chinese BBs for them RC airsoft tanks, but will also work fine on anything made for airsoft.

Anyway, here's a picture TO END ALL questions of scale differences between 1/1 and 1/6:


It's self-explanatory of which one in this image is 1/1 and which one is 1/6:
- The huge, threatening-looking one is 1/1.
- The small, tiny-sized comrade is 1/6.
KAPISH?

Also, PLEASE, stop PM'ing about where to get em' (to those of you who did so).

I WON'T ANSWER SUCH QUESTIONS AND ALL SUCH PMs WILL RECEIVE INSTANT TOILET FLUSH.

If you're wondering where I got em':

THIS will be my answer.
