everything XD its a springer, my rifles and side arms could shoot through the crap those are made of! save up for a G&G combat machine well worth it.
Do you only have £40 saved up, or more than that? If you're not that far off enough for a G&G then don't bother, and if you are then still don't get the springer because it will just take even longer to save up. If your mum is only letting you get a springer, get a springer pistol or something instead that is a bit cheaper at least.
What everyone else said, no point dropping that cash on a springer that will only further delay your CM, unless it's with your own cash and then asking your parents for a AEG for Christmas
DO NOT BUY THAT, I REMEMBER BUYING THAT EXACT GUN ABOUT 8 YEARS AGO WHEN I WAS PROBABLY THE SAME AGES AS YOU. IT BROKE AFTER 1 FIRST SHOT. DONT BUY A SPRINGER PIECE OF CRAP SAVE UP FOR AN AEG
Remember is only fires 1 shot, then you have to cock the firing bolt back (It was really stiff) then it will fire again. Its made of cheap plastic that is prone to snapping. If you just want it to put on your wall or something and never shoot it, its probably okay. but if you actually want to skirmish it will be usless, plus it is porbably over 350fps if it has a powerful spring like the one i had.
Good idea tri-shots should be fine as long as you don't f*ck about with them, mine mysteriously sort of broke and was only firing on every second pump and then not consistently. I think paint must have got inside or something. Don't get the ASG shells though, I think you get a pack of four or five but only like 2 or 3 worked for me and I have heard other people say the same thing.
