Alexander does a video for Airsoft Sports to show the various features and operation of the East Crane Hi-Capa 5.1 Combat Master TTI GBB pistol. The East Crane's Hi-Capa 5.1 Combat Master TTI EC-2102 is an airsoft replica of the Hi-Capa 5.1 pistol, crafted from aluminum alloy for added strength and precision. It features ABS plastic handle cheeks, a picatinny rail for additional equipment, and markings on the body.

The stippling on the handle ensures a comfortable and reliable grip, while the blowback system and controls mimic its combat counterpart. It has slide release and magazine release buttons on the left side, and two fuses: a standard double-sided flag fuse and an automatic safety lever. The gun also includes an adjustable hop-up and a 100 mm inner stem.
