I just called Customer Service and they said that non of the sights that Springfield has on other guns are compatible (bummer).Hello,
Does Springfield offer a replacement rear site for the Echelon that has a square notch (not the U notch)?
Thank you,
Part of the problem is that the sight swill insert, but will not be the right height for the optics cut. The Echelon uses a mid sized height sight that is not quite a suppressor sized tall sight, but not a shorty either.
