Tokyo Marui Hi-Capa 5.1 GBB Gas Pistol - Black

Tokyo Marui Hi-Capa 5.1 GBB Gas Pistol - Black

One of the best-known competition-oriented gas pistols, combining Tokyo Marui's consistent hop-up performance, large gas magazine and easy handling.

The Tokyo Marui Hi-Capa 5.1 is a gas blowback pistol designed around both practical shooting and airsoft use. Its wide double-stack-style grip accommodates a large-capacity magazine, while the textured grip panels and shaped trigger guard provide secure support for both hands.

The functional grip safety and ambidextrous thumb safety support familiar 1911-style operation. Deep serrations at the rear of the slide make cocking easier, while the white-dot front sight and fully adjustable rear sight provide a clear and adaptable sight picture.

Competition-oriented handling

The Hi-Capa 5.1 is particularly well suited to Action Air and other dynamic shooting disciplines. Its large magazine, adjustable sights and consistent hop-up provide a strong factory platform for Standard Division use and for builds intended for Open Division.

The adjustable hop-up allows the BB trajectory to be tuned for different BB weights. Combined with Tokyo Marui's lightweight slide and efficient gas system, this provides responsive cycling and consistent practical accuracy.

Polymer and metal construction

The slide and lower grip frame are manufactured from impact-resistant ABS polymer, while the middle frame is made from metal. This construction keeps the moving slide light for fast blowback operation while adding rigidity and weight around the central frame.

The outer barrel, hammer and several functional internal components are also metal. The slide and frame feature moulded or engraved-style markings that complete the competition-inspired appearance.

Accessory rail option

The frame can be fitted with the model-specific 20 mm accessory rail for mounting a compatible pistol light, laser or optic-mounting system. Installing the original rail requires the designated mounting procedure and tools.

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 work 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.
