The CZ Scorpion sub-gun is a blowback-operated semi-auto with cold hammer-forged barrel. Its muzzle features 1/2x28 threads hidden underneath the factory flash hider, meaning users can fit either 1/2x28 or 18x1 accessories to the muzzle. Equipped with 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. It has a polymer frame with a QD sling swivel pocket integrated into the rear sling attachment point. Simple and reliable, the Scorpion not only has ambidextrous controls, its non-reciprocating charging handle is swappable and trigger reach is adjustable. This S2 Micro model has a 4.5" barrel, flash can muzzle device, Magpul MBUS back-up iron sights and SB Tactical folding brace.
