Hi-Capa Xtreme .45 Full Auto, pistol replica GBB [Tokyo Marui]

Tokyo Marui Hi-Capa Xtreme .45 Full Auto GBB is a gas-powered pistol replica designed for dynamic full-auto fire, very fast blowback cycling, and the high-quality operation of Tokyo Marui gas systems. The design is based on the Hi-Capa platform in a full-auto configuration, combining a compact frame with a high-capacity magazine and a pronounced slide cycling character.

Design and construction

The model is based on the Hi-Capa 4.3 platform, but the Xtreme version features redesigned slide serrations, markings, and a distinctive visual finish.

The 172 mm slide is equipped with front and rear serrations, improving grip during charging and allowing confident manipulation even when wearing gloves.

Selected components are finished with a silver hard chrome coating, giving the replica a more aggressive and sporty appearance.

The construction is designed to limit the ingress of dirt into the internal mechanism. A 20 mm Picatinny rail is integrated under the barrel, allowing the mounting of tactical accessories such as flashlights or lasers.

The design uses compact control elements, including a skeletonized hammer, a single-sided safety lever, and a shortened grip safety to reduce the risk of snagging on gear.

A lanyard attachment point is located at the rear of the grip for securing a retention lanyard.

Gas system and blowback

The replica uses a newly developed gas blowback system designed specifically for full-auto operation. It achieves a significantly faster slide cycle compared to standard semi-auto models.

The system delivers a rate of fire of approximately 25 BBs per second while maintaining strong slide movement and a pronounced recoil impulse during continuous fire.

Tokyo Marui platforms are known for their high gas system efficiency, smooth operation, and consistent performance under intensive use.

The replica is equipped with an adjustable hop-up system, allowing the BB trajectory to be tuned according to ammunition type and environmental conditions.

The model operates exclusively in full-auto mode, supporting very aggressive close-range engagement.

Ergonomics and handling

The rear sight assembly is designed to withstand the stress generated by continuous firing cycles.

Grip ergonomics and control placement support intuitive handling during fast-paced use.

The replica is equipped with a grip safety and a manual thumb safety that secures the firing mechanism.

Performance and specifications

The muzzle velocity is approximately 290 FPS, matching compact GBB platforms intended for fast close-range operation.

An internal barrel length of 95 mm supports consistent hop-up interaction and repeatable shot performance.

Overall length is 200 mm, with a height of 157.5 mm and a width of 35 mm.

Weight is approximately 510 g without a magazine and around 835 g with an inserted empty magazine, providing a lightweight and well-balanced setup for rapid handling.

Magazine

The included 31-round magazine features increased gas capacity, supporting stable operation during continuous fire.

Tokyo Marui magazines are known for their precisely engineered valves, smooth gas delivery, and consistent BB feeding throughout the firing cycle.
