AKS-74U Tactical Rifle Replica CM.113B Eshooter ETU, GEN-2[CYMA]

CYMA Platinum CM.113B is a tactical AKS-74U (AKSU) airsoft replica developed as part of the cooperation between Taiwangun and CYMA. The model combines a full metal construction, GEN-2 V3 gearbox, and a programmable Eshooter ETU, supporting high performance, fast trigger response, and extensive configuration options. The set includes two Mid-Cap magazines, making the replica ready for use straight out of the box.

Construction and design

The replica features a full metal construction. The receiver, receiver cover, barrel, fire selector, sight base, trigger, gas block components, bolt carrier, gas tube, and muzzle device are made from steel and aluminum, enhancing durability and realism. The pistol grip and magazines are made of durable polymer.

The standard handguard has been replaced with a lightweight aluminum rail system compatible with 22 mm Picatinny accessories, allowing the installation of flashlights, lasers, foregrips, and other equipment. The aluminum gas tube cover also features an integrated Picatinny rail.

A side-mounted optics rail enables the installation of compatible red dot sights and optics. The replica is fitted with a side-folding PT-1 Gen.2 stock featuring adjustable length and an ergonomic cheek rest.

Gearbox V3 GEN-2

The upgraded V3 GEN-2 gearbox has been developed for intensive use and high cyclic rates. The reinforced shell features improved bearing seats and radiused stress points for increased durability.

The air system utilizes CNC-machined components, including reinforced piston and cylinder heads, a CNC aluminum nozzle, and a piston with a full steel rack. Power transmission is handled by CNC 13:1 gears operating on 8 mm steel ball bearings.

The integrated QSC (Quick Spring Change) system allows spring replacement without opening the gearbox, simplifying maintenance and power adjustment.

High Torque motor

The replica is powered by a neodymium High Torque motor that supports rapid trigger response, stable operation, and efficient performance during demanding gameplay.

Accuracy and consistency

The AK-style slider-adjustable hop-up chamber allows precise tuning of BB trajectory.

A 255 mm long 6.05 mm precision inner barrel supports improved grouping and consistent shot performance at medium and longer engagement distances.

Eshooter ETU

The programmable Eshooter ETU (Electronic Trigger Unit) expands the replica's functionality with additional firing modes, including Burst and Binary. The system offers five levels of pre-cocking adjustment, Active Brake functionality for gearbox stabilization, and compatibility with High Torque, High Speed, and brushless motors. Integrated protection features help safeguard the motor, gearbox, and battery against jamming, over-discharge, and improper voltage levels. Programming can be completed in three simple steps, while the reset function is activated by holding the trigger for eight seconds.

Battery compartment

The battery compartment is located under the receiver cover and is designed for stick-type batteries.
