In this video, Mach Sakai, a champion practical shooter, tests out a custom Western Arms Hi-Capa Race Gun that was modified by Mister Tokoro. The gun features a muzzle, sight XT-6, front part slide processing, slide pull, and short trigger. Sakai shows how to grip the gun, inject gas, and insert BBs. He then performs a high capacity live firing and measures the initial velocity and firing sound of the gun. He also competes in a Steel Challenge Round Bout and an APS Cup Bullseye. At the end, he shares his impressions of the gun and chats with some people in Setagaya.
