A.T.9 K Airsoft Submachine Gun Replica (Green Gas Powered) - Black [Golden Eagle]

The A.T.9 K gas-powered airsoft submachine gun replica by Golden Eagle is a compact model designed for dynamic airsoft games, particularly at short distances and in CQB environments. The replica combines a metal receiver with a CNC-machined aluminum handguard, a factory-installed NPAS power adjustment system, and ambidextrous controls with a folding, height-adjustable stock, supporting comfortable handling and allowing users to customize the configuration to their preferences.

Construction and Materials

The Golden Eagle A.T.9 K features a compact design, measuring ~370 mm with the stock folded and ~585 mm with the stock extended. Its compact dimensions make the replica easier to maneuver in confined spaces, change positions quickly, and handle during dynamic CQB engagements.

The upper receiver, outer barrel, and muzzle device are made of metal. The handguard and stock are manufactured from CNC-machined aluminum, while the controls, trigger, and pins securing the trigger mechanism components are made of steel.

Steel is also used in internal mechanism components, including the valve knocker, hammer, auto sear assembly, and fire selector. Additionally, the rear section of the mock bolt carrier features steel reinforcement.

The pistol grip is made of high-quality polymer, while the stock buttpad features a rubber cover that supports stable shoulder positioning.

An engraved serial number is located on the upper receiver, below the ejection port cover.

Ergonomics and Ambidextrous Controls

The A.T.9 K features steel ambidextrous controls arranged similarly to those found on AR-15 platform rifles. These include the fire selector with safety, bolt catch, charging handle, and magazine release.

The control layout provides intuitive handling for users familiar with the AR-15 platform, while the ambidextrous design allows comfortable operation for both right- and left-handed players.

The enlarged magazine well facilitates faster reloads by reducing the need for precise magazine alignment. Users can guide the magazine into position more efficiently, particularly during situations requiring quick reactions.

The enlarged trigger guard makes it easier to operate the trigger while wearing gloves, while the flat steel trigger supports consistent finger placement during rapid follow-up shots.

The pistol grip contains an internal storage compartment for spare batteries or other small accessories. Access to the compartment is secured by a hinged cover.

Folding Stock with Height Adjustment

The replica features a folding stock made of CNC-machined aluminum, allowing the overall length of the submachine gun to be reduced when moving through confined spaces.

The stock mounting system uses a RIS rail, enabling vertical position adjustment. Users can adjust the stock height relative to the receiver according to their preferences, shooting position, and sighting setup.

The replica features three QD sling attachment points. Two are located on the stock, while the third is positioned at the rear of the lower receiver, directly below the stock mounting point.

This arrangement allows users to select a sling attachment configuration that suits their preferred carrying setup.

Mounting System and Accessory Configuration

The front section of the replica features a 115 mm CNC-machined aluminum handguard equipped with the M-LOCK mounting system. It allows the installation of compatible foregrips, tactical flashlights, and other accessories according to user preferences.

A RIS rail runs along the top of the upper receiver, allowing the installation of red dot sights, magnifiers, or mechanical sights.

The outer barrel features a 14 mm counterclockwise (CCW) thread, allowing the installation of a compatible suppressor or tracer unit.

Gas System and NPAS Adjustment

The A.T.9 K gas-powered submachine gun replica comes factory-equipped with an NPAS (Negative Pressure Adjustment System), which allows power adjustment by changing the ratio of gas directed toward the hop-up assembly and inner barrel to the amount supplied to the blowback mechanism.

The factory muzzle velocity is ~250 FPS. The NPAS system allows users to adjust the replica's power output according to game requirements and the limits established by individual airsoft fields.

The NPAS adjustment screw is located inside the nozzle. A 1.5 mm Allen key is required to change the settings.

Hop-Up Adjustment System

The Golden Eagle A.T.9 K features a hop-up system with its adjustment mechanism positioned in the front section of the replica.

The adjustment screw is located above the outer barrel, between the barrel and the handguard. This positioning provides direct access to the adjustment mechanism from the front of the submachine gun, making it easier to fine-tune the settings during use.

Adjustment is performed using a 5 mm Allen key. The hop-up system applies backspin to the BB, allowing users to adjust its flight trajectory according to the airsoft BBs being used.

The replica features an inner barrel measuring 85 mm in length with a diameter of 6.01 mm, which guides the BB during firing.
