I'm new to this whole ordeal so apologies if this is obvious but I'm looking online at an mp40 for 30 quid and in the description it says single fire has to be cocked after every shot It's a spring gun aswell I was wondering if this meant that it was a semi auto or would I have to pull the bolt back every time I want to shoot and if this is a waste of money https://www.justbbguns.ie/german-mp40-airsoft-bb-gun/ Here is a link to it if someone can elaborate for me
