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.

The Tokoro Mini Gover Long Barrel Custom WA GBB Pistol, the only one of its kind in the world, has been reviewed by Mach Sakai. The review covers various aspects of the pistol including its overall length and weight, the magazine, front and rear sights, engraved markings, slide pull, trigger pull, safety device, and grip. The review also delves into the normal disassembly and assembly of the pistol. The Mini-gover live firing, gas consumption, initial velocity measurement, and firing sound measurement are also discussed.

Mach Sakai goes over Mr. Tokoro's Marui V10 Custom GBB Pistol to find the enhancements did to it. The Tokyo Marui V10 Ultra Compact is a gas blowback airsoft pistol that faithfully reproduces the V10 pistol with a Novak slide. The company has accurately reproduced the features of the V10 Ultra Compact, including its distinctive ports and variations in surface finish. It also features a blowback engine based on the M45A1, allowing for sharp and powerful recoil despite its small size.

Mach Sakai takes a look at the improvements done by Mr. Tokoro on the Tokyo Marui Foliage Warrior Gas Blowback Pistol. This is a 4.3 GBB pistol that does away with the ACU pattern grip panel of the original Foliage Warrior and went for the traditional 1911 grip look and with cuts to the slide and a custom gas magazine.
