So I just got my new stock today and have been in the process of assembling my gun. Everything fit fine up until the point that I'm putting the receiver cover on and it was nowhere near flush with the 2 bolt holes. I thought this may be the new stock but as I'm looking at a way to file the stock down to make it fit I think that maybe it isn't the stock and maybe it's the receiver cover. So I put the receiver cover back on the factory stock. The only way it ever fit was because the factory stock flexes enough for it to fit. This new stock however does not give at all. I put the receiver cover on a flat surface and it's pretty far off from being flat. I can't find my camera or I would take pictures of it. I'm going to have to file down the receiver cover because there's no way I could hammer it out or anything. We'll see though, hopefully I get it figured out without making it too much of a hassle.
