Forged from 7075-T6 aluminum and precision machined to work with all DPMS-pattern .308 components.

This upper was suggest by my buddy, after receiving it I know why. This is a quality piece and I like the integrated hand guard mount.

I'm never going back to a "regular" upper

You get Aero Precision quality and you don't have to shim the barrel nut! I'm never buying a regular upper again!
