Frequently Asked Questions

How do you properly zero AR-15 offset iron sights?

Zero offset iron sights by ensuring the rifle is canted at the exact 45-degree angle. Use a stable platform like a bipod, fire shots to find the point of impact, and use the FORS (Front Opposite, Rear Same) method for adjustments until point of aim matches point of impact.

What is the FORS acronym for sight adjustments?

FORS stands for Front Opposite, Rear Same. When adjusting sights, you move the front sight opposite the direction you want the bullet to go, and the rear sight in the same direction as the desired impact shift.

What distance is recommended for zeroing 5.56 NATO AR-15 offset sights?

While 25 meters can be used for quick confirmation, longer distances like 50 meters, 36 meters, or 100 meters are generally preferred for zeroing 5.56 NATO rounds to achieve a more practical battle zero.

Why is the 45-degree cant important when zeroing offset sights?

The 45-degree cant is critical because offset sights are designed to be used at that specific angle. Zeroing them while holding the rifle at this exact angle ensures they will be accurate when deployed in a fight or transition.
