TOKYO MARUI - M4A1 CARBINE (EVOLT Series AEG)

Separate-Type Mech Box

By dividing the mech box into a “cylinder assembly” and a “gear box,” the upper receiver set and lower receiver set can be completely separated. This enables a far more realistic takedown, even though it is an electric gun.
A dedicated cover is included to protect the internal mechanisms when storing or transporting the separated upper and lower sets.
The cylinder uses a smooth fluorine-lubricated plating and is a small-bore, minimal-capacity design.

EG1000BR Motor

The gun is equipped with the newly developed EG1000BR motor, featuring a bearing-equipped reverse type.
Additionally, the design of the three gears that transfer the motor’s rotation to the cylinder (bevel, spur, sector gears) has been completely revised. Instead of conventional sintered construction, MIM (Metal Injection Molding) is used. The spur and sector gears also feature a 4 mm shaft diameter, resulting in improved durability, smoother rotation, and significantly enhanced quietness.

M-SYSTEM Type II

The gear box incorporates the M-SYSTEM Type II, an optimized version of the M-SYSTEM used in the next-generation electric MP5 series, redesigned specifically for the M4.
The MCU (microcontroller unit) monitors sensor data and voltages throughout the system to control firing mode selection and motor rotation. It also detects damage or abnormalities and stops operation automatically, providing both performance and safety.

Pursuit of External Realism

A non-functional real firearm was measured to accurately reproduce the dimensions of the upper/lower receivers, handguard, grip, buffer tube, and more.
The receiver features Cerakote, offering strong coating durability and scratch resistance.
The grip uses reinforced polymer to achieve both thinness and durability, and it is intentionally left unpainted to replicate the authentic texture of the real firearm.

Barrel Change System

The standard 14.5-inch outer barrel can be swapped for the included 11.5-inch barrel extension.
This barrel change system allows the user to choose their preferred barrel length.
By removing the flash hider, any 14 mm CCW muzzle accessory can be installed.

New Chamber & Magazine Mechanisms

New mechanisms have been developed, including:

• Stabilizer Nozzle: stabilizes nozzle position to improve accuracy

• Inner Elevation System: applies upward tension inside the magazine to prevent feeding issues

• One-by-One Loading System: the shutter inside the magazine closes after each round is fed, preventing BBs from entering the chamber until the next shot

Together, these innovations improve both safety and operating performance.

Realistic Operation

Realistic handling is reproduced, including charging the first round by pulling the charging handle.
When the gun runs empty, the dummy bolt locks open and the trigger becomes inactive, just like the real firearm.
If the magazine is removed while rounds remain, pulling the trigger will reproduce the behavior of firing a round left in the chamber—without actually firing a BB for safety reasons.

Realistic Pressed-Steel Magazine

Capacity: 81 rounds
A dedicated magazine with a steel-pressed outer shell is included.
It features the Inner Elevation System to prevent feeding failures, and the One-by-One Loading System, which closes the shutter after each BB enters the chamber so that no next round is fed until firing.
