Duration: 37:50

This video details the build process and component selection for a custom AR-10 rifle, emphasizing precision shooting and versatility for competition and hunting. The presenter highlights key parts like the Criterion barrel, Aero Precision receivers, Arken optic, and Geissele trigger, explaining the rationale behind each choice for optimal performance and reliability. Specific attention is given to AR-10 platform compatibility issues and the importance of selecting matching upper and lower receivers.

Quick Summary

Building a precision AR-10 requires careful component selection. Prioritize matched upper and lower receivers (e.g., Aero Precision M5), a quality barrel like the Criterion 20" .308 M118 LR for 175-grain ammo, and an optic with a zero stop such as the Arken SH4 J Gen 2. A two-stage trigger and a stable bipod are also essential for long-range accuracy.

Frequently Asked Questions

What are the key considerations when building an AR-10?

When building an AR-10, prioritize matching upper and lower receivers from the same manufacturer to ensure compatibility. Select a quality barrel suited for your intended ammunition, like a Criterion 20-inch .308 M118 LR for 175-grain bullets. A reliable optic with features like a zero stop and a good two-stage trigger are also crucial for precision.

What makes the Arken SH4 J Gen 2 optic suitable for precision shooting?

The Arken SH4 J Gen 2 optic excels due to its Japanese glass, providing superior clarity and light transmission. Its 50mm objective lens gathers more light, and features like parallax adjustment and a zero stop allow for precise aiming at various distances and quick return to zero.

Why is barrel selection important for an AR-10 chambered in .308?

Barrel selection is critical for accuracy. A Criterion 20-inch .308 M118 LR barrel, for instance, is specifically designed for 175-grain projectiles, optimizing velocity and stability for long-range engagements. Using ammunition that matches the barrel's specifications leads to tighter groups and better performance.

What are the advantages of a two-stage trigger in a precision rifle build?

A two-stage trigger, like the Geissele SSA-XE, offers a distinct advantage by providing a smooth take-up phase followed by a crisp, clean break. This allows the shooter to establish a solid grip and sight picture before the shot, minimizing unintentional movement and improving overall accuracy.
