Worst come to worst email the site and ask them if they dont know save up and get a good mp5.
Every one here will tell you that you get what you pay for in airsoft. Sure there are some good cheap things, certain shot guns and what not. But in general your first AEG shouldnt be a cheap little thing. Ive seen and had over a dozen friends want to get into this sport only to be put off because they bought cheap things at the start and didint like having to replace there guns ever month.
