Golden Eagle Type 870 M8878 Compact Tactical Gas Shotgun

Golden Eagle
  • Ghost Ring
  • TM Compatible
  • 3rnd/6rnd Shot

This compact and awesome Gas Airsoft Shotgun is constructed almost entirely from Alloy, with the exception of a Polymer Pistol Grip and Stock. It takes standard Airsoft Shotgun Shells and is powered by an Internal Gas Tank just like the TM870 models. If you're looking for a highly realistic and grin-inducing Airsoft Shotgun experience, then this should be very high on your list.

Full description


The Type 870 series from Golden Eagle are manufactured from Alloy to be as realistic as possible, using only Polymer for the Pistol Grip and Stock as per the real thing. The M8878 Model is a replica of the shorter M870, with the addition of an AR Pistol Grip and Buffer Tube / Sliding Stock assembly. This makes it way more useful in a variety of locations as you can set the Stock length to suit the situation at hand, and it also looks cool as heck.

As per the Tokyo Marui series of Gas Shotguns, these replicas take standard Airsoft Shotgun Shells and can fire either a 3rnd or 6rnd Burst of BBs with each pump. To set this feature, simply pull back on the pump and move the slider behind the mock bolt. To load the Shotgun you only need to press the release lever for the Breech Door, push the Shotgun Shell into place till it clicks, close the Breech Door and get pumping! Each Shotgun Shell holds 30rnds, for a total of 10 shots when on the 3rnd mode, and is filled using the Speedloader to force BBs into the front of each Shell.

The M8878 Model is a Railed/Tactical version of the Sawn-Off M870, and features a 20mm Rail on the Receiver for you to mount optics, or anything 20mm compatible that you're brave enough to install up there. This Rail System comes with a Ghost Ring Rear Ironsight installed, which is very pleasant to use. The Magazine Tube for the Shotgun can act as a shell holder should you wish, and can be accessed by unscrewing the front cover. A Thumb-Through Safety can be found near the Trigger, which will block the Trigger and prevent the Shotgun from firing. The Pistol Grip is like you would find on a standard AR, and can easily be replaced with most aftermarket AR GBB Pistol Grips. The Stock is a Sliding design that can be set to one of six positions, and also conceals the Gas Tank inside the Buffer Tube. To fill the Gun with gas, simply extend the Stock to access the Inlet Valve on the underside of the Buffer Tube. On the rear of the Receiver you will also find a QD Sling Socket which can be used to install a Quick Release Sling Loop.

Included in the box are 3 x Airsoft Shotgun Shells, Speedloader, Instruction Manual and the gun itself. If you're looking for a highly realistic and well-constructed Airsoft Shotgun that has the ability to fire up to 6 BBs per shot and is powered by Gas for a realistic Pump Action, then the Type 870 M8878 Compact Tactical Gas Shotgun will be of great interest to you.

Special Instructions

These Gas Shotguns rely on smooth, mechanical movement. For this reason, it is incredibly important that you lubricate and maintain your Shotgun using a Silicon Lubricant, such as the ones listed below. Failure to do this could cause issues. 

Abbey Silicone Gun Oil 35 Spray

NUPROL Premium Silicone Gun Oil 

We also highly recommend the use of Maintenance Gas when the Shotgun is not in use, to help keep your seals as fresh as possible.

*Please note that the M-LOK Pump Handle is too tight to the Magazine Tube to be able to install Accessories, and is purely for aesthetics.
