Description
Tokyo Marui Hi-Capa 4.3 GBB Gas Pistol - Black
A compact Hi-Capa gas pistol with responsive blowback operation, adjustable hop-up and a 31-round magazine.
The Tokyo Marui Hi-Capa 4.3 is a compact gas blowback pistol designed for fast handling in confined spaces and dynamic shooting situations. Its shorter 4.3-inch configuration makes it easier to manoeuvre than the full-length Hi-Capa 5.1 while retaining the familiar Hi-Capa grip, controls and large-capacity magazine.
The textured grip provides a secure hold, while the shaped trigger guard supports controlled two-handed handling. A functional grip safety is located at the rear of the grip, and the pistol’s straightforward controls make it easy to operate.
Compact and responsive construction
The slide and lower grip frame are made from impact-resistant ABS polymer, while the middle frame is metal. The lightweight polymer slide supports fast and gas-efficient cycling with the lower-pressure gas specified by Tokyo Marui, while the metal middle frame adds rigidity and weight to the central structure.
Front and rear slide serrations make the slide easier to operate. The white-dot front sight and clear rear sight provide a quickly acquired sight picture for close-range and dynamic shooting.
Adjustable hop-up
The adjustable hop-up allows the BB trajectory to be tuned for different BB weights. Combined with Tokyo Marui's consistent gas system, this helps provide reliable practical accuracy in airsoft games and Action Air use.
Accessory rail
The frame includes an accessory rail for mounting a compatible pistol light, laser or other rail-mounted accessory.

Note regarding Tokyo Marui construction: Tokyo Marui airsoft guns are designed to comply with Japanese law, industry safety standards and the manufacturer's own safety requirements. The Japanese muzzle-energy limit for a conventional 6 mm airsoft gun is approximately 0.989 joules, so Tokyo Marui products are designed to operate below this limit with a safety margin.
The polymer slide, magazine valve, hammer mechanism, nozzle, floating valve, barrel and other gas-system components are designed to operate together with the lower-pressure gas specified by Tokyo Marui. The pistol is not designed with an easy factory method for significantly increasing muzzle energy without changing the operation or mechanical loading of the system.
Higher-pressure gas may increase wear, cause malfunctions, alter muzzle energy or damage the polymer slide, nozzle and other internal components, particularly in warm conditions. Using gas stronger than specified by Tokyo Marui is at the user's own risk and may affect the product warranty.
