[Eeyore]

So yet again I rin into another problem trying to use a crane stock om my M4.
So I get the new buffer tube and stock from Hunag and it fits great now but... As I was screwing the buffer tube into the receiver the screw stripped, badly. Now I can't move it either way and the head of the screw has more of a circle than a star or square head. I tried to use a chisel and a mallet to put a grove in the screwhead for a flathead screw driver, but the plate the screw is up against is made so the screwhead is flush with it. Does anyone know of a way I can get the screw out of the buffer tube? Its a good five inches down. The only thing I can think of is to cut the buffer tube down with a hacksaw and try to drill the screw. Please anyone who has an idea or has had this problem help me out. I'd rather not detroy this new buffer tube.
