Long Fei's video details his modification of a VFC T91 SOC GBB, building upon his previous T91 projects (Guo Hun T1, MWST1, WT1). He showcases the VFC model's realistic design and performance before demonstrating the disassembly and modification process, which involves installing a Dial Defense handguard, grip, and stock, along with a magazine well, larger magazine release, and a 13.7-inch handguard.

As we have reported earlier, a good number of Taiwanese airsoft manufacturers have revved up production of gas blowback rifles to meet local demand as well for the Milsimers who prefer gas blowbacks due to their more realistic operations. In this video, Vega Force Company presents the T91 SOC Gas Blowback Rifle which is based on Taiwan military's service rifle and the BCM Air MK2 MCMR Gas Blowback Rifle which is already available at airsoft retailers in East Asia.
