Variant & Year-of-Manufacture Notes

Original-condition examples with matching serials, factory boxes, and manuals trade at the top of the range for the model.

Modern factory loads from American, European, and Asian manufacturers all run well in this platform, and reloaders enjoy a wide range of bullet and powder combinations.

What’s a Used Aero Precision M5 .308 Complete 20" Worth?

Private-sale ranges for a working, no-rust M5 .308 Complete 20" in 2026 fall in four bands:

• Beater / heavily used: $350–$525 — significant wear, action functional, may need cleaning or minor service
• Average / honest used: $475–$725 — normal handling marks, mechanically sound, ready to shoot
• Excellent / lightly used: $650–$1000 — minimal wear, clean bore, original box and paperwork a plus
• New-in-box or unfired: $825–$1300 — at this price, the calculation usually flips toward buying new instead

Add a premium for documented early-production examples, original box and accessories, or limited-run variants. Subtract for refinished surfaces, aftermarket modifications a buyer would have to reverse, or signs of hard use.

Who Buys It?

The typical Aero Precision buyer profile includes AR-15 enthusiasts, 3-gun shooters, value-conscious tactical buyers. The rifle format and the .308 Win chambering further focus the audience.
