Q&A for Aero Precision M5 20in .308 CMV Complete Upper Receiver w/ Flash Hider & ATLAS S-ONE Handguard — 29 Questions & 30 Answers

This does not include a BCG or charging handle.

Yes, the Aero Precision M5 20in .308 CMV Complete Upper Receiver will include an A2 style, birdcage flash hider that can be removed and replaced with aftermarket muzzle devices threaded 5/8x24.

Most firearms chambered in .308 Winchester can also shoot 7.62x51. However, to be safe I recommend contacting the manufacturer to confirm the Aero Precision M5 20in .308 CMV Complete Upper Receiver w/ ATLAS S-ONE Handguard can fire 7.62x51 safely.

The buffer assembly that I would recommend for this upper receiver is the Aero Precision M5 Buffer Kit. It was specifically designed to work with the M5 lower and upper. It includes the 308 buffer spring, 308 carbine buffer, end plate and lock nut, and a milspec buffer tube. You can find the Aero Precision Buffer Kit using the following link:

Yes. The Aero Precision M5 20in .308 CMV Complete Upper Receiver is designed to fit with DPMS pattern 308 lower receivers.

As long as it is a DPMS pattern 308 lower, the Aero Precision M5 20in .308 CMV Complete Upper Receiver should fit. It will not be compatible with a standard 5.56 AR15 lower.

No. The Diamondback DB10 uses the Armalite A-pattern. The Aero Precision M5 20in .308 CMV Complete Upper Receiver will only fit to DPMS pattern 308 lower receivers.

Yes, this will be compatible.

This will weigh 5.5 pounds.
