* This model is licensed by KAC and bears the trademarks and markings of the KS-1.

The licensed Knight's Armament WE13 13" replica from WELL PRO was developed for users looking for a high rate of fire and fast trigger response. Equipped with a programmable ETU system, quick spring change system, the replica supports dynamic gameplay and allows users to adapt its performance to individual preferences.

Performance and electronics

The combination of a High Torque motor, optimized gearbox, and advanced electronic control system allows the replica to achieve a rate of fire of up to 25 BBs per second while maintaining smooth operation.

The programmable ETU system allows adjustment of firing modes and pre-cocking settings across five levels. The system also supports BURST and BINARY modes. In semi-automatic mode, users can select either single-shot or two-stage firing, while in automatic mode it is possible to choose between full-auto fire and a three-round burst.

Gearbox and internal components

The gearbox utilizes reinforced components designed for operation at high rates of fire. The piston is equipped with a steel tooth rack, while the reinforced polymer piston and cylinder heads support the air seal of the pneumatic system.

The nozzle helps maintain stable airflow, supporting consistent performance and shot-to-shot repeatability. The design is further enhanced by a quick spring change system that allows power adjustment without complete gearbox disassembly.

Construction and ergonomics

The receiver and major external components are manufactured from durable and lightweight Nylon Fiber Polymer. This construction provides rigidity and durability suitable for regular use, whilst keeping the weight and cost low.

The M-LOK handguard allows the installation of compatible tactical accessories such as weapon lights and foregrips without significantly increasing the weight of the setup.

The replica features ambidextrous controls, including the magazine release, bolt catch, and fire selector. This configuration supports comfortable operation for both right- and left-handed users.

AR platform

The model is based on the AR15 / M4 platform and utilizes a modern control layout characteristic of contemporary rifles in this family. The arrangement of mounting points and the overall ergonomics allow quick installation of compatible accessories and intuitive handling.
