The KS-1 is a GBBR airsoft rifle based on the AR15 platform. Its construction combines realistic gas system operation with controls positioned for convenient right- and left-handed handling.

The external metal components were manufactured using CNC machining. With every shot, the gas blowback system cycles the bolt carrier assembly, producing a noticeable mechanical response and supporting realistic handling.

12.8-inch URX handguard with M-LOK system

The airsoft rifle is equipped with a 12.8-inch URX handguard. M-LOK slots positioned on several surfaces allow equipment such as a flashlight or foregrip to be mounted, enabling the accessory layout to be adapted to the user's preferences.

A full-length RIS mounting rail runs along the top of the upper receiver and handguard. It allows the installation of a red dot or riflescope.

Adjustable NPAS system and hop-up

The metal bolt carrier assembly cycles after every shot. Its weight contributes to the noticeable operation of the gas blowback system when the trigger is pulled.

The NPAS system allows the power output to be adjusted according to temperature, BB weight, and the limits applied during a particular game. The hop-up adjustment is located on top of the upper receiver, within the mounting rail, allowing the BB trajectory to be corrected without disassembling the airsoft rifle.

Reinforced steel components and trigger mechanism

The internal system uses proprietary reinforced steel components developed by the manufacturer, including parts of the trigger mechanism. Their construction supports the resistance of the internal parts during regular and intensive use.

The trigger mechanism features short travel, a fast reset, and a clearly noticeable break point. This facilitates firing follow-up shots at short intervals.

The inner barrel has been matched to the KS-1 configuration to support accuracy and shot-to-shot consistency. The airsoft rifle also uses a proprietary magazine design inspired by VFC and MWS AR15/M4 systems, developed to support efficient gas delivery and correct operation of the GBB mechanism.

Ambidextrous handling and SF-style stock

The KS-1 features an ambidextrous charging handle, magazine release, fire selector, and bolt catch. Controls positioned on both sides of the airsoft rifle facilitate right- or left-handed operation without requiring the user to change their primary grip.

The adjustable SF-style stock allows its length to be adapted to the user's build and tactical gear configuration. Fully collapsing the stock facilitates transport, storage, and handling in confined spaces.
