We took the small compact CZ Scorpion EVO 3 S1 sub-gun and made it even shorter and more compact!  By adding a CZ-USA 5.3″ barrel and the HB Industries Micro/K conversion kit, along with a SB Tactical SBA3 Pistol Brace, we made the CZ Scorpion EVO 3 an extremely small sub-gun with a 5.3″ threaded barrel (1/2×28 TPI) and a HK 3-Lug Mount.

CZ-USA Scorpion Evo 3 S1

Finally available for public consumption is the much anticipated Scorpion sub-gun.  Imported as a pistol, it is a blowback-operated semi-auto in 9mm that originally came from the factory with a short 7¾” barrel.  Equipped with the newly designed low-profile sights, its rear sight has four different aperture sizes for everything from close quarters to way out there.  The sights ride on an 11” Picatinny rail perfect for mounting optics.  This item also comes with a QD sling swivel pocket integrated into the rear sling attachment point which can be installed after removal of the M4 buffer tube adapter.

Simple and reliable, the Scorpion not only has ambidextrous controls, its non-reciprocating charging handle is swappable and reach to the trigger is adjustable.

This CZ pistol comes with two 20-round magazines.
