A picture of your rifle would be good! We are not sure if you are speaking about the traditional A-2 Removable Sight, A stand alone or flip up!
And as NCH mentioned they have the Dominator 2 which was specifically designed for use with the EOTech units. If you plan on using the Standard A-2 Removable Sight you will need a Cantilever Mount to tactically mount the EOTech on one of those! Sounds like a great rifle and I am sure you will enjoy it!
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.
