I've recently bought one of these for quiet squirrel bashing. Interesting fully moderated little gun which has been cerakoted. I have a few issues with it. Has anyone got one in good working order? If so, I would love some advice or even pictures of the underside of the bolt and also the main spring that drives the firing pin. Mine has been tinkered with and I'm trying to work out if a series of problems stem from either a reworking of the bolt shroud or whether it's a wrong spring that's been inserted.
Any help greatly appreciated.
