Korean YouTuber Crescent tested the Dekai Mk.17 SCAR-H EBB Gel Blaster, a gel blaster model featuring selectable safe, semi-automatic, and full-automatic firing modes. The device incorporates a realistic blowback effect during firing and a functional bolt catch, alongside a magazine priming mechanism. Its design includes an extendable stock, metal charging handle and trigger, metal internal gears, a full metal barrel assembly, and a piston rack. Power is supplied through an XT30 battery plug.
