to put more detail in the second answer a molle belt or a plce belt either one can hold mag, utility, grenade and radio pouch you can even turn them into bandoliers B)
1) because you dont need to be.. the ukara scheme is setup to make both shops and our lives alittle easier when buying rifs as you are not 18+ you cant by law buy any airsoft rifle so it would be pointless you being on the database.
2) as someone already said a molle vest is the best way to go as you can swap the pouchs around making it useful if you decide you want more or less mags etc. if you want something lighter and dont need much storage space then just a normal tactical vest will do the job fine.
