HI mate, oh yeah I remember now that you took your first one back..
You should easily notice the hop-up wheel yourself when you remove the slide but I'll try sorted out a picture later if you like?

It's a shame your new one don't rack properly, can't you remove the black from the sights and take it back to the shop, although I know that would be a pain in the but as it's the second one but your entitled to..

By it not racking back properly though mate what's it doing? Not feeding or getting stuck etc?

I must admit although I stopped buying airguns and turned to airsoft because of spares being available I'm very tempted on this beretta and think it could be my next gun in October..
