I downloaded the 25 Meters Zeroing Target M16A2.  

How big do I print this target up?  

How big are the military's targets that they use to zero in their A2's?

Thanks,

The target sheet is 8.5x11 (that cicle on the target is roughly 1.5" across).

However its not recommended that you zero at 25 meters.  This is a better system - that properly calibrates the elevation dial:

While you're at that site you can download the 50yard version of the target (again it's a 8.5x11 sheet with the circle being 3" across).  Targets are found in the Documents section under 'Targets'.

Hey Forest,

Thanks a million,

You know what I'll be doing this weekend.
