Assembly no problem, but rifle must be in good condition. I Saw
one in thailand about SGD 45 but half metal half plastic,
adjustable butt, and other assecories like scope, etc. there got
alot of such stuff. But i din buy cos later go through the metal
detector at changi.... beep beep beep. Die 
Mp5 also got in thailand. all airsoft. But got metal parts and
scope. I think if u want to buy such stuff thailand and hk most
suitable. But i think bring in sure kanna caught esp. after sept 11
