I bought a 702 with the carbon fiber stock for my wife am having the same issue with the last shot hold open sticking.After reading this post i checked and sure enough charging bolt slamming back hard enough to bend the metal behind it am wondering if maybe a bad spring .
I bought my wife a 702 plinkster liked the lightweight and the carbon fiber stock looks good.She started having jamming issues but was not jamming ,the last shot hold open was sticking open,which is weird to me .Anyone have any idea what this is?
