Design details
The Scorpion Evo 3 is a blowback operated carbine evolved from a Slovak prototype submachine gun developed by Laugo. Chambered in 9×19mm Parabellum, the Scorpion EVO 3 is mostly polymer, making it a lightweight, compact submachine gun designed to be easily maneuvered in confined spaces. The A1 variant features a standard left-side non-reciprocating charging handle, although it is ambidextrous and can be switched from side-to-side. It also has an ambidextrous select fire switch, giving the operator the choice of "safe", semi-automatic, three-round burst, or fully automatic fire, while the S1's switch only features "safe" and semi-automatic fire. The standard version comes equipped with a folding, adjustable and fully removable stock for transport. The handguard is lined with multiple Picatinny rails for the addition of attachments such as grips, sights, flashlights, and lasers. The handguard on the American semi-automatic offering features M-LOK attachment points, with a single Picatinny rail on top.
