The SR-25/Mk 11/M110 is a better way to get the same job done.

A lot of that is the semi-auto action, keeps knocking the ole zero off. But the NCO that ran me through the M-21 always swore that if the shooter double-checked his zero after firing a sequence, then the problem could be avoided. The zero loss is the major reason why you so seldom see semi-auto sniper rifles. What a lot of people forget is that the M-21 was never really designed for sniping duties. It was designed for sharpshooter or what the service calls designated marksmen, a trained infantryman engaging targets inbetween 500-900 meters with sustained, accurate fire. In this role, the M-21 is hard to beat. Its when you compare it to dedicated sniper rifles that the M-21 falls short.
