Quick Answer
To zero your AR-10 for optimal hunting accuracy, use a ballistic calculator or a shooting app to determine the best zero, and then use a laser bore sight or a traditional method to establish the point of impact. Place a target at 100 yards and fire multiple rounds to verify the zero. Make adjustments as needed to achieve the desired point of aim.
Choosing the Right Zero
When choosing a zero for your AR-10, consider the type of hunting you’ll be doing and the terrain you’ll be in. For hunting larger prey, a 200-yard zero is often preferred, as it allows for effective shots at longer ranges. However, if you’re hunting smaller game or in dense woods, a 100-yard zero may be more suitable. It’s also essential to consider the type of ammunition you’re using and the ballistic characteristics of the cartridge.
Setting Up Your AR-10 for Zeroing
Before you start zeroing your AR-10, make sure it’s properly sighted in with the rear sight or optic. Use a laser bore sight or a traditional method to establish the point of impact, and then set up a target at the desired zero distance (usually 100 yards). Fire multiple rounds to verify the zero, and make adjustments as needed to achieve the desired point of aim. A common starting point for the windage is to adjust the rear sight 1-2 MOA left or right from the point of aim, and then make further adjustments as needed.
Finalizing Your Zero
Once you’ve established your zero, it’s essential to verify it with multiple shots and conditions. Shoot from different positions, angles, and with different ammunition to ensure that your zero is consistent. Also, make sure to check your zero regularly, as environmental changes (such as temperature and humidity) can affect the trajectory of your bullets. By following these steps and being methodical in your approach, you’ll be able to achieve a reliable and accurate zero for your AR-10.
