Fifth Generation Hobby Shop does an unboxing, review, and testing of the SRC Airsoft Titan 2.5 Full Metal CO2 Powered Revolver. They highlight its features, including its 2.5-inch barrel, six-shot capacity, full metal build, and adjustable fiber optic sight. The CO2-powered revolver uses a 12g cartridge, can fire both steel and plastic balls, and comes with initial ammunition and accessories like a shell loader and extra CO2 cartridges. The demonstration covers the loading process and concludes with firing tests at a short range, done in both the single and double action firing modes.
