The legendary submachine gun from Germany's H&K, now with a standard fixed stock

The MP5 A4 has arrived as the latest addition to the Next Generation Electric Gun series, featuring a fixed stock!

Equipped with the high-safety "M-SYSTEM," it utilizes an FET (electronic trigger system) where a microcontroller comprehensively monitors and controls the FET, FC, battery, and motor. This model faithfully recreates 3-round burst capabilities, improves trigger response, supports the upcoming genuine LiPo battery, and pursues absolute realism in both exterior finish and operability.

Key Features

Equipped with Shoot & Recoil Engine

• Pulling the trigger engages an approximately 300g weight that simulates the bolt during firing, delivering intense recoil throughout the entire body. It also features an auto-stop system that halts firing when the magazine is empty, and a bolt release mechanism that allows you to resume firing by pulling the bolt handle. This model is designed to pursue realism in both operation and performance.

3-Round Burst Reproduction

• In addition to semi and full-auto firing, this model perfectly reproduces 3-round burst firing. The selector, which can be operated from either the left or right side, is linked by an axle passing through the mechanical box, ensuring smooth rotation and a satisfying, distinct click.

FET Equipped

• Replacing the traditional mechanical switch, an FET (electronic switch) is utilized. Compared to mechanical switches, this reduces current loss at the contact points and improves the response time from pulling the trigger to firing the BB.

• The newly developed "M-SYSTEM" features a microcontroller (MCU) that comprehensively monitors and controls the FET, FC (Fire Control), battery, and motor. By monitoring data from seven sensors and various voltages, it not only handles firing mode switching and motor rotation control but also enhances safety by detecting damage or abnormalities in various components to halt operation.

Pursuit of External Realism

• Many metal parts, such as the upper receiver, feature a powder-coated finish that closely mimics the texture of the original firearm. Additionally, the handguard, lower receiver, fixed stock, selector, and cocking lever are molded from high-strength nylon resin, closely resembling the materials used in the real firearm.

Enhanced Structural Rigidity

• By reviewing the parts configuration of the cocking handle and utilizing high-strength nylon resin, it is now possible to perform the "HK slap"—striking the locked cocking lever to release it. Furthermore, the sliding retractable stock features a new structure, increasing both realism and rigidity.

Adjustable Rear Sight

• The drum-type rear sight allows for vertical adjustments using the included rear sight adjustment tool, and horizontal adjustments using a Phillips screwdriver (*), just like the real thing. *Phillips screwdriver is not included. Please provide your own.

Realistic Stamped Magazine

• 72-round capacity. Includes a magazine with a steel-pressed outer case that features all-around welding along the seams, just like the real item. *This magazine is not compatible with other MP5 series models, such as the Standard Electric Gun type.
