Step 3: Choosing the Right Zeroing Distance

When I'm getting ready to zero my M4 iron sights, picking the right distance is crucial. After having discussed the importance of selecting high-quality iron sights and adjusting them accurately in the previous sections, it's time to talk about the optimal distance for zeroing. The term "zeroing" refers to the process of adjusting your sights so that your point of aim matches your point of impact at a certain distance. This is essential for achieving accurate shots.

According to military standards, particularly for those who follow the Army's guidelines, the most common zeroing distance for M4 iron sights is 25 meters. This is because the trajectory of 5.56 rounds fired from an M4 flattens out significantly at this range, making it an ideal starting point for zeroing. You'll often find M4 25m zero target for iron sights available, specifically designed for this process. Using a target designed for this range can simplify the process, as it has the necessary adjustments marked on it.

Choosing the right zeroing distance isn't just about tradition or following guidelines; it's about understanding the ballistics of your chosen ammunition and how they affect your point of impact at various ranges. Knowing how your rifle behaves at 25 meters can provide insights into how it'll perform at longer distances. If precision at longer ranges is your goal, starting at 25 meters can give you a solid foundation to adjust from.

When it comes to adjusting the sights, knowing how many clicks to adjust m4 iron sights for elevation and windage is key. Remember, each click of adjustment on standard M4 iron sights like the A2 Rear Iron Sight or the Carry Handle Rear Sight typically equates to about 1/2 MOA (Minute of Angle). This is roughly equivalent to a 1/2 inch movement at 100 yards, but the actual impact will depend on your zeroing distance and the specific sights you're using, like the HK Style BUIS or Micro Flip Up Backup Sights from Ozark Armament. Always refer to the manufacturer's guidelines for exact adjustment specifics.
