E-1,
Yes, I use the G G&G riser on one of my AR-15's, not to clear the
front sight, because it doesn't have one, but to extend the length of flat top
rail forward for use of long optics with large objective lens off the bench,
and keep the rings at medium height. Not exactly cheap at $75 but
worth the price. Thanks for the link.
