Primary Weapons Systems MK109 Mod 1-M complete upper receiver in 300 Blackout with a 9.75-inch barrel.
PWS builds its uppers around a long-stroke piston instead of direct impingement — less gas and fouling back into the receiver, which matters more on a short 300 Blackout than on anything else. This is the MK109 Mod 1-M with a 9.75″ barrel.
