AR10 RE-ZERO

Published on August 20, 2024
Duration: 10:59

This video demonstrates the process of re-zeroing an AR-10 rifle chambered in .308 Winchester at 100 yards. The instructor highlights the importance of securing optic turrets after adjustments to prevent them from backing out due to recoil, a problem he experienced previously. The guide covers firing initial shots, observing impact, and making precise adjustments using MIL-based turret values to achieve a dead-center zero.

Quick Summary

Securing optic turrets on a rifle is vital to prevent them from loosening due to recoil, which can cause a loss of zero. The AR-10 in this video features a 20-inch Criterion barrel and an ARken 6-24x scope, zeroed at 100 yards using MIL adjustments.

Frequently Asked Questions

Why is it important to secure optic turrets on a rifle?

Securing optic turrets is crucial because recoil from shooting can cause them to loosen and back out. This leads to a loss of zero, meaning your shots will no longer hit where you aim, requiring a complete re-zeroing process.

What is the typical zero distance for an AR-10 rifle?

While zero distances can vary based on intended use, this video demonstrates re-zeroing an AR-10 at 100 yards. This is a common distance for establishing a baseline accuracy for many rifle platforms.

How are adjustments made when zeroing a rifle scope?

Adjustments are made by turning the optic's turrets, which correspond to windage (left/right) and elevation (up/down). The amount of adjustment is typically measured in MOA (Minute of Angle) or MILs (Milliradians), with each click moving the point of impact a specific amount at a given distance.

What components make up the AR-10 rifle in this video?

The AR-10 features a 20-inch Criterion stainless steel barrel, a Geissele SS AE trigger, a Tribe Defense bolt carrier, an ARken Optics 6-24x scope, and a FAB Defense RAFT stock. It is chambered in .308 Winchester.
