Re: Rear sight base threads

I cleaned the threads this morning again and looked with magnification. It appears only the very top thread is distorted such that the screw won't start. I am tempted to use a fine dremel point to grind this down a bit and get the screw started, BUT I know I will regret that. I also checked the thread pitch and diameter with a caliper. 5/32 in x 26 tpi SEEMS to be right. SO, I am ordering this tap from England, and will hope it works. My wife wants me committed.
