The Aero Precision M5 20in .308 Complete Upper Receiver will work with DPMS Gen 1 High Profile lowers. The Aero Precision M5 20in .308 Complete Upper Receiver should work with a R25 lower.

We build our 308 M5 platform to the AR308 pattern, with a DPMS High Profile (.210) Tang rail and 1-7/16 x 16 TPI. Please note that our .308 products are machined to AR .308 specs, which is similar but not the same as DPMS Gen 1. Unfortunately, because there is no set standard, we are unable to guarantee compatibility with any other manufacturer’s products within this platform.
