Frequently Asked Questions

What is the primary advantage of building an Aero Precision M5 based on the DPMS LR-308 standard?

Building on the DPMS LR-308 standard for the Aero Precision M5 provides significantly greater aftermarket support and customization options compared to proprietary AR-10 platforms, allowing for a more tailored build.

Why was a Ballistic Advantage 18-inch Hanson profile barrel chosen for this Aero M5 build?

The 18-inch Ballistic Advantage Hanson profile barrel was selected to save weight compared to the heavier profiles typically found on factory Aero M5 uppers, contributing to a more manageable precision rifle.

What trigger is recommended for an affordable precision build like the Aero M5 SAPR?

The Schmid 2-stage trigger is recommended as a favorite affordable precision trigger option, offering good performance for its price point in AR-platform builds.

What were the initial performance observations for the Aero Precision M5 .308 build?

Initial reliability was poor with 7.62x51mm ammunition, possibly due to a break-in period or under-gassing. However, accuracy testing later yielded sub-MOA 5-shot groups with match-grade ammunition.
