I have never had a problem I have a tight allen wrench.I did replace one of them with a stainless steel bolt.I would take a fine file and slot the head then use a screwdriver to remove if its really tight.

I received my replacement screw in the mail and everything has been working great since. I replied back to Al Coon after he told me my screw was in the mail describing the whole ordeal. To make a long story short apparently the original windage screw had somehow had the threads messed up a little. In any case, he emailed me back again today saying he put a whole mounting bracket in the mail for me.

Now that is what I called customer service. Needless to say I'll use Copper John Sights from now on and reccomend them to anyone and everyone.
