The brand new 9mm Patriot Sub Gun (VIDEO)

The POF PSG 9mm, or Patriot Sub Gun, is a tactical AR-15-type semi-auto-only pistol/select-fire submachine gun.

The Sub Gun has an extremely compact system due to its self contained recoil system that does not require the traditional AR buffer tube.

At just 16.3-inches overall length, its designed to be used with a single point sling attached to the rear of the firearm much like an MP5K. The new POF PSG accepts Colt style 9mm magazines and comes with an MSRP of just $999.99.
