Airsoft pistol "Maverick" in FN 5-7 design

Selling from an estate this airsoft pistol by "Maverick", visually modeled after the well-known Five-Seven. Caliber 6mm BB, F in a pentagon. Handling like a real one: insert magazine, chamber, fire. It has a blowback system, meaning the slide moves back with each shot, also has a really impressive recoil for an airsoft. However, after the last shot the slide does not stay back, not sure if this is a defect or intended.Includes a second magazine.Sale without warranty and only with age verification!
