Incorrect taper angle, not proper a1 spec - Tiger Rock A1 Stock Buttpad Screw with See-Through Hole

This took me a lot longer than it should have, to discover that this was the root of all my problems! I was thinking it was the stock, or maybe the buffer tube length causing my stock to have enough a gap to swivel and and crimp-bend my detent spring (for takedown pin). I ruined several springs, and currently have several different buffer tubes on order and in the mail, before accidently noticing that this screw has a 45 degree angle which gives it fewer threads and doesn't allow for a proper seat with the buttpad. This is extremely disappointing as the material and finish on this part is superior to most others I have seen, especially in all the A2 lengths.
