Is the Aero Precision M4E1 Pro recommended for precision shooting?

Based on the review, the M4E1 Pro is considered more of a duty rifle for heavy use rather than a dedicated precision platform. While it has good build quality, its accuracy performance after refurbishment did not meet sub-MOA claims, suggesting it's better suited for general-purpose or defensive roles.
