We get to watch another brief review of ICS Airsoft's Hi-Capa Gas Blowback Pistol offering, the Hi-Capa Challenger, as done by Airsoft Europe. Already available in the market, it features the TDC Hop-Up Chamber, MASTER MODS R-Hop System, REVO.II High-Performance Valve System, and has the RMR & DOC mount to mount micro optics. It's compatible to some TM-spec Hi-Capa parts.
