Yes it can make it. Only certain real steel equipment, gear, and accessories are ITAR protected. Yes buy it elsewhere, or it will likely cost double or more by the time it's in your hands.
Here's a suggestion though. Even those look cool, they are heavy and hot, not great for airsoft. I'd recommend a smaller more high speed, more maneuverable plate carrier. Not to mention, many of those extra pads are not worn in real scenarios, due to the extra rigidity and weight.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
