From Ascalon Arms:
Extended magazine catch for CZ Scorpion EVO 3 is designed with focus on ergonomy, intuitive handling and maximum shooters comfort.
It's made with MJF technology (multi-jet fusion) out of PA12. The magazine catch is a solid piece of material giving the user possibility to modify its shape.
The surface is rough allowing a sure grip, preventing your finger from slipping off.
The package includes the magazine catch body with spring pin installed and one spare 4x30 mm spring pin.
This part is NOT compatible with CZ Scorpion EVO 3+!
