I just recieved my new hs precision stock in the mail, right away i noticed they got the " web" finish all over the rear tang area. I had you use fine grit sand paper to gently and lightly rub over the tang to completely remove it to expose the aluminum tang. Question is when i tighten the recoil lug screw the rear tang of the receiver isnt touching the stock unless i screw it in drawing the reciever to the aluminum. Is this something i need to be worried about???
