Installing a tapco t6 on my ak. I was first off kind of surprised to have to drill, not sure why that wouldn't come drilled from the factory.

So I drill them down to length with the included bit, and these screws won't go in more then half way. Also they only gave me one screw. Anyway, long story short, the head of one of the screw heads twists off. Just under hand power.

So now I have part of a screw logged in the stock. I would have to drill it much larger to still use this. Do you think ctd will take it back or am I screwed (no pun intended lol)

Any ideas?
