Tokyo Marui Hi-Capa 4.3 Xtreme Full Auto GBB Pistol
The Tokyo Marui Hi-Capa Xtreme is a full-automatic gas blowback pistol based on Tokyo Marui’s compact Hi-Capa 4.3. Pull the trigger and it keeps firing for as long as you hold it, giving you a hand-held burst of firepower that is a lot of fun on the range and genuinely useful when clearing rooms.
Tokyo Marui is the Japanese manufacturer behind many of the most influential designs in airsoft, and its gas blowback pistols are widely regarded as the benchmark for out-of-the-box accuracy and consistency. A huge range of aftermarket parts is designed around Tokyo Marui pistols, so they are easy to maintain and upgrade. The Xtreme takes the proven Hi-Capa 4.3 and turns it into a full-auto machine pistol, while keeping the light weight and compact size that make the 4.3 so easy to carry.
Full-auto performance
This pistol fires in full-automatic only, so every pull of the trigger sends a stream of BBs downrange. The double-stack magazine holds 31 rounds, which empties quickly in full auto, so short, controlled bursts are the key to making the most of each magazine. Carrying a couple of spare magazines is strongly recommended, and in cooler weather keep them warm in a pocket, as full-auto fire cools the magazine quickly.
Please check your site’s rules before using it in a game: some sites restrict full-auto fire from sidearms or in close-quarters areas.
Build and design
The slide and frame are injection-moulded from reinforced polymer, designed to resist impact damage while keeping the pistol light. Slide serrations give a positive grip when racking it, and a skeletonised trigger and hammer give the Xtreme a lean, competition-inspired look. An integrated lower Picatinny rail takes a pistol light or laser.
How it works
The Hi-Capa Xtreme is a gas blowback pistol. Gas is filled into the magazine, and each pull of the trigger releases a measured amount to fire the BB and drive the slide back. The moving slide gives a real kick in the hand, cocks the action for the next shot and, on most models, locks back when the magazine runs dry, so you build the same reloading habits you would with a real pistol.
Like every gas pistol, its performance depends on temperature. Gas pistols cycle crisply on warm days; in the cold, pressure drops, so keep a spare magazine in an inside pocket and pace your shots during rapid strings so the magazine has a moment to recover. Good quality BBs of a consistent weight give the flattest, most repeatable flight.

Compatibility
Use Tokyo Marui Hi-Capa magazines; please ask us before buying spares so we can confirm fit with this model. Fires standard 6mm BBs; 0.20g to 0.25g suit Tokyo Marui gas pistols well.
Tokyo Marui gas pistols are designed around lower-pressure HFC134a-type gas. Stronger green gas can put extra strain on the slide and internals, so a low-power gas is the safer choice. Use only gas made for airsoft guns; never use lighter fluid or butane. Holsters made for Hi-Capa 4.3 pistols are the best starting point.
Care and maintenance
Gas blowback pistols reward a little regular attention. After a day’s play, wipe the slide, frame and magazine down with a lightly oiled cloth to remove dust and moisture, and run a cleaning rod with a clean patch through the inner barrel every so often to keep accuracy consistent. Use only gas made for airsoft, and put a drop of silicone oil on the magazine fill valve and outlet seal from time to time to keep them supple and leak-free.
Don’t overfill the magazine; a short, steady fill is enough, and you will hear and see when it is full. For storage, leave a small amount of gas in the magazine to keep the seals pressurised, store the pistol and magazines at room temperature, and avoid leaving them in a cold car or direct sun. In cold weather keep spare magazines warm in a pocket, as gas pressure drops noticeably as temperature falls. Use good quality seamless 6mm BBs, as cheap or misshapen BBs are the most common cause of jams and hop-up wear.
Who is it for?
The Hi-Capa Xtreme suits experienced pistol shooters who want something different, CQB players looking for close-range firepower, and anyone who enjoys a full-auto pistol on the target range.
