Maxim pdx 556 upper black - Maxim Defense Industries MDX 505 PDX/SCW Compatible URG Upper Receiver

Great system. I love the fact that this Maxim PDX upper works with my non-PDW equipped AR lowers. Something my Q Honey Badger upper can never do. It’s nicely universal in that respect. The upper functions smoothly suppressed and un suppressed. Cycling is more violent obviously with my silencer attached but without the can rounds eject perfectly at 3 O’clock. If you’re in the market for a pint sized barrel with a raised 416 style upper this is what you should grab before they’re all gone.
