The KB Glock 17 Gen 3 EBB gel blaster handgun is reviewed in this video by Crescent, listing its features, specifications, and performance. The reviewer notes its realistic design with a metal slide and outer barrel, and its electric blowback (EBB) system, which provides strong recoil. He also covers its optic-ready design, support for a threaded outer barrel, and the ability to convert it for use with 6mm BBs.
