Flip from the small aperture to the large “0-200” aperture for a 200 meter zero.Use the 6/3 setting with the 25/300 meter trajectory as BZ.

Method of use originally conceived for 14.5″ M4 barrel carbines, but adaptation for other barrel lengths is addressed.Intended as a method for combat shooting over varying distances, the soldier can simply aim at his rifle into the middle of an enemy at an unspecified distance and know that he will hit within a lethal zone without worrying about holding over or under the target.įour Different Ways To Zero And Employ A2 Sights Are Discussed: The US Army Method: It will provide the flattest trajectory over the longest distance and allows you to aim at center mass of the target and achieve hits within +/- X inches out to a distance of Y meters or yards. It isn’t an actual specific sight setting, but rather a philosophy of employing a zero distance that will keep the point-of-aim and the bullet’s actual path within a certain acceptable margin out to the longest possible range. The term “Battle Zero” (or “Battle Sight Zero”) is a misleading term. The Battle Zero (BZ) Philosophy Is Discussed: This is a good review, even if you think that you already know everything about them (I thought that I knew everything about A2 sights, but I learned a great deal while researching this).

There is very basic review of ballistics and a review of A2 sights and how to use and adjust them. You will probably want to save your time and energy by skipping the reading for the zeroing technique and rifle/ammunition combinations that don’t pertain to you.Ī2 Sights, Their Parts, And How To Adjust Them Are Discussed: USMC method – 16″ barrel – M855 ammunition) and zero accordingly. In that section, find the rifle barrel length and ammunition type that matches yours (ie. You will be served by reading about the battle zero philosophy and the four different zeroing techniques here in the spoiler section, decide on which zeroing technique will best serve your needs, and then skip down to that technique’s detailed description. As a reader it will be easy to get bogged down and overwhelmed by all of the minutia that I’ve bombarded you with. When I started researching this subject to satisfy my own curiosity I had no idea of how complex it would get, especially having to figure out zeros and trajectories for different barrel lengths and ammunition weights.
