I received my new front sight and it stands about a quarter inch lower than the original. I haven't taken it to the range yet, but I'm positive this will solve the problem.
The folks at MI have been fantastic throughout this issue. I agree with the poster in a thread below who doubted this was an MI issue, but there is no doubt that MI stepped up and solved it.
We should all remember when shopping for accessories that there aren't many companies which would go to this length to solve a problem they probably didn't create.
Thank you again, so much.
