RE: EOTech Issue on AR
BC,
The only thing I can think of is a sight mount made by B-Square. It isn't the greatest but it will mount the sight high enoug to clear the front post. It is also removable. I have one and it has never failed me other than to loosen up every 50-75 rounds or so. It is quick release.
I think those eotech's normally go on the new fancy AR's that don't have any posts and have all the rails and such.
