Quick Answer
To sight in your AR-10 before hunting, use a consistent shooting position, set your sights to match your ballistic data, and fire a series of shots at a target to determine your point of impact. This process helps you accurately zero in your rifle. Regular practice ensures your AR-10 performs as expected in the field.
Choosing the Right Ammunition
When selecting ammunition for your AR-10, consider the type of hunting you’ll be doing and the distance you’ll be shooting. For longer shots, use a heavier bullet with a higher ballistic coefficient to ensure a flat trajectory. A good starting point is a 168-grain match bullet, which is suitable for hunting deer and other medium-sized game at distances up to 500 yards.
Zeroing Your Sights
To zero your AR-10’s sights, start by setting your rear sight to the “parallax-free” position or 1/4 inch above it, depending on your specific sight model. Then, adjust your elevation knob in 1/4-MOA increments until the point of impact is on the aiming point. This process typically requires 3-5 shots to find the optimal zero.
Maintaining Your Rifle
Before heading out on a hunt, perform a series of checks to ensure your rifle is in good working order. Inspect your sight, barrel, and action for any damage or wear. Clean and lubricate your rifle as needed, and make sure your ammunition is properly stored and loaded.
