FatBoy said:That's not just an M1a problem. My DCM AR did that with the JP single. When Jeff Corn couldn't fix it I put a Jewell in there. I have since moved to Geissele for new builds, but you really don't have that option as far as I know.
Here is a link to the lens kit. As you have an engineers mind, you can search Miso lens and get a much better description of how it works and why it'll work with the M1/M1a rear sight where others may not.

Thanks, I will take a look. I am encouraged with my one test of the standard front sight with the wide post and that may be all I need for now but I need to know what else is available if needed.
