Golden Eagle Alpha Tactical Production A.T.P. Doomsday Gas Pump-Action Airsoft Shotgun - Gray

Green Gas • Selectable 3-Shot / 6-Shot • Triple Inner Barrels • 30-Round Shells • M-LOK • Fixed Hop-Up

The Golden Eagle Alpha Tactical Production A.T.P. Doomsday Gas Pump-Action Airsoft Shotgun combines a shell-fed multi-shot gas system with an aggressive modern tactical configuration built for players who want something very different from the conventional airsoft rifle.

Powered by Green Gas, the A.T.P. Doomsday uses three inner barrels and selectable 3-BB or 6-BB firing modes. Each 30-round shotgun shell therefore provides approximately 10 trigger pulls in 3-shot mode or 5 trigger pulls in 6-shot mode.

Metal/resin construction is paired with a machined aluminum front end, one-piece aluminum top rail, M-LOK accessory mounting, removable hand stop, AR-style pistol grip, ambidextrous QD sling mounting and a six-position tactical stock.

Overview

The Doomsday takes Golden Eagle's multi-shot gas shotgun system and surrounds it with a modern tactical chassis. Rather than using a conventional single inner barrel, it employs three inner barrels to simultaneously launch multiple BBs with each trigger pull.

A selector allows the shooter to choose between 3-shot and 6-shot operation. The manual pump action prepares the system for the next shot, giving the Doomsday the manipulation and shell-loading style players expect from an airsoft shotgun.

Its adjustable M4-style stock and AR-style pistol grip provide familiar handling, while the M-LOK front end and Picatinny-compatible rail space support a wide range of compatible airsoft accessories.

Historical Background: The M870 Tactical Shotgun Influence

The A.T.P. Doomsday belongs to the broad family of airsoft shotguns styled around the famous pump-action tactical shotgun concept, with retailers identifying the platform's visual lineage with the Remington M870 Tactical family.

The original Remington Model 870 was introduced in 1950 and became one of the most recognizable pump-action shotgun designs in the world. Its basic action has been adapted over the decades into sporting, defensive, law-enforcement and tactical configurations.

Modern tactical interpretations often replace traditional furniture with accessory rails, adjustable stocks, pistol grips and modular mounting systems.

The Golden Eagle Doomsday pushes that modernized appearance much further with its AR-style controls and furniture, machined aluminum components and M-LOK accessory mounting.

Important: The Golden Eagle A.T.P. Doomsday is an airsoft replica and should not be interpreted as a claim that this exact configuration is an issued or factory Remington firearm.

Selectable 3-Shot / 6-Shot System

The centerpiece of the Doomsday is its selectable multi-shot system. Instead of firing a single BB with every trigger pull, the shotgun can simultaneously launch either three or six BBs.

• 3-Shot Mode: approximately 10 trigger pulls from a 30-round shell
• 6-Shot Mode: approximately 5 trigger pulls from a 30-round shell

Three-shot mode is the ammunition-efficient setting. Six-shot mode produces a denser multi-BB discharge at the cost of consuming the shell twice as quickly.

30-Round Shotgun Shell Magazine System

The Doomsday feeds from removable 30-round airsoft shotgun shells.

Three shells are listed as included with the GE8905GY package, providing up to 90 BBs of total loaded shell capacity when all three shells are loaded.

For replacement shells, use compatible Golden Eagle 30-round gas-shotgun shell magazines and verify compatibility with the GE8905GY platform before ordering.

Recommended BB Weight & FPS

For gameplay, Gray Dragon Airsoft recommends starting with high-quality seamless 0.25g 6mm BBs.

A current U.S. retailer lists the Green Gas GE8905GY at approximately 260–300 FPS with 0.20g BBs. Because Green Gas performance changes with temperature, gas pressure and testing conditions, actual chronograph results may vary.

Use 0.20g BBs when a field requires that weight for chronograph testing, but follow the field's specific multi-shot shotgun chrono procedure.

Do not use the substantially higher published velocity figures for the separate GE8905GY-CO2 model when describing this Green Gas shotgun.

Green Gas Operation

The GE8905GY is the Green Gas version of the A.T.P. Doomsday.

Gas powers the multi-shot firing system while the player manually cycles the pump between shots. Gas performance can vary with ambient temperature, fill pressure, seal condition and other factors.

Keep the gas system properly maintained and follow Golden Eagle's operating instructions.

M-LOK & 20mm Accessory Mounting

The Doomsday's modern external design incorporates a machined aluminum M-LOK front end and a large one-piece aluminum top rail.

This provides mounting space for compatible airsoft optics, illumination devices and other field-legal accessories.

A removable aluminum hand stop is also included, giving the player another option for configuring the pump area.

6-Position Tactical Stock & AR-Style Grip

Instead of traditional shotgun furniture, the Doomsday uses an M4-style stock adapter with a six-position telescoping stock and AR-style pistol grip.

The adjustable stock changes the shotgun's listed overall length from approximately 720mm to 800mm, allowing the user to tailor the length of pull for comfort and maneuverability.
