The Strike Industries CZ Scorpion EVO Selector Switch is both an ambidextrous or non-ambidextrous package (3 piece package) which allows the shooter to configure the setup needed while adding short but wide easy-to-reach controls. Grooves are designed onto the selector switches to ensure control even in wet conditions. Retain factory ambidextrous controls or use the included optional third piece if you want the selector switch only on one specific side. Made from durable and lightweight polymer, the drop-in Strike Industries CZ Scorpion EVO Selector Switch paired with the Strike Industries CZ EVO pistol grip (sold separately) will give you improved ergonomics over the originally designed CZ factory parts.FeaturesAmbidextrousSerrations for non-slip OperationCompatibility: all CZ Scorpion EVO modelsPackage Contents:x2 Selector Switchx1 End Capx2 M3x12 Screwx1 M1.5 Hex Keyx1 Loctite
