Equipped with a folding SB Tactical arm brace, this Scorpion Pistol wears the forend of its larger brother, the Carbine. With the same 7.7” pistol barrel, owners can unscrew the 5” KAK Flash Can and install most pistol suppressors under the handguard, keeping the overall length down. Dual threads of 18x1 and 1/2x28 make fitting a suppressor simple. Current production Scorpion pistols lack the 3/4" sling slot on the left side of the action that is present on earlier variants. The CZ Scorpion EVO 3 S1 Pistol is legally classified by the ATF as a pistol, and is intended by CZ-USA to be used as a pistol. Under current federal law and ATF policy attaching a stock to this pistol - or attaching a device which is then used as a stock or intended to be used as a stock - constitutes the making of a short-barreled rifle which requires registration with ATF and the payment of the applicable tax. Users of the CZ Scorpion EVO 3 S1 Pistol bear the sole responsibility for ensuring their use of the firearm complies with all local, state, and federal firearms laws.
