Acccording to the exterior ballistics calculator at [url]http://www.realguns.com/[/url], impact for 55gr ammunition at 50yds for a 100yd zero with sights 2.6 inches above a 14.5 inch barrel should be .08 inch BELOW aiming point.

Iron sights are 2.6" above bore centerline, I'm pretty sure the TA01NSN is higher. My ELCAN is 78mm above bore centerline -- it's in the ELCAN manual, making it pretty easy to compute. -- Chuck
