Thanks chaps.
Perhaps I should have given more research to my impulse Ares purchase!.. But hey ho... ( It does feel very nice and shoots pretty decent - ish)..
I'm relatively new to Airsoft, are there any vids / tech you can recommend on the differences of set ups / electronic controls?. I will be opening my gun up next week some time anyway so I'll get an idea of the Ares set up then anyways. I can't imagine they are terribly complicated but I can understand how even small measurement differences will change set ups.
I'll do some more googling too...
