- Full metal construction
- 3 or 6 BBs per shot
- Removable gas tank
If you plan on tactically taking names at your next CQB skirmish, the Tokyo Marui M870 Tactical Gas Airsoft Shotgun is the perfect tool! This close replica of the real steel Remington Model 870 Tactical shotgun features a black polymer stock, a Picatinny top rail and a set of ghost ring iron sights.
It also offers 3 or 6 BBs per shot and a very fast action; far easier to cock than comparable spring shotguns, especially at speed! Inside, this shotgun is equipped with a fixed HOP-up optimised for 0.25g BBs. This may limit your range, but remember, this is a shotgun; up close and personal is where you want to be!
The TM M870 Tactical Gas Airsoft Shotgun is powered by standard green gas stored in a removable gas tank, allowing you to carry multiple tanks in a pouch for long-duration operations. If you need something to dominate close quarters, you can't ask for better than this!

Description
If you're planning on owning your local CQB site, the Tokyo Marui M870 Tactical Gas Airsoft Shotgun is an excellent choice! It's based on the iconic Remington M870 shotgun with black polymer furniture, a 20mm Picatinny top rail and a fixed stock. This beast certainly packs a punch with its 3 or 6 BB per shot firing modes and hefty full metal build!
Starting at the front, we can see the menacing 12-gauge style bore of the M870 Tactical; an intimidating prospect to face in CQB! The barrel tapers towards the tip in classic shotgun style and features realistic calibre markings on the left side, reading 12GA. 2 ¾” OR 3”. This refers to the real M870’s ability to chamber both standard 2 and ¾ inch shells along with 3-inch magnum shells, one of the enviable characteristics which make real shotguns such versatile platforms.
Below the barrel, we have the mock magazine tube, which is where the shells are stored in a real pump action shotgun. In Airsoft form, this tube can hold spare shells, but it is impractical to unscrew the front cap to access them whilst on the battlefield. Like the outer barrel, it is constructed from alloy for a realistic feel. At the front, we can see the authentically replicated front cap, which is textured for easy removal.
The pump grip rides around the mock magazine tube, connected to the alloy pump arms, which themselves connect to the action through the front of the receiver. It features a ribbed design to improve its gripping qualities, even in wet weather. It is long enough to comfortably grip in most shooting positions and sits far enough back from the muzzle that there is no risk of you racking the M870 and then accidentally blasting 6 BBs straight into your palm!
Moving rearwards, we come to the alloy receiver, which is relatively featureless, just like the real thing. On the right side, we can find the mock ejection port, showcasing a detailed mock bolt carrier with a mock extractor stamped in. Rack the pump back to reveal the load selector switch, offering either 3 BBs or 6 BBs per shot. Using the 3 BB mode will slightly extend range and FPS, while the 6 BB mode will reduce FPS and widen the spread; perfect for engaging moving or multiple targets.
On the bottom of the receiver, we can find the controls of the M870 Tactical. These take the form of the shell door release, located on the left side of the trigger guard and the ambidextrous push-through safety catch, located at the rear of the trigger guard. The shell door release is serrated for optimal gripping qualities and, when pressed, will open the shell port door and eject your shell, ready for a rapid reload!
The safety catch is simple but functional, locking the trigger when the catch protrudes at the right side, revealing a white ring around its circumference. When the Tactical is hot, the safety catch will protrude on the left, revealing a surrounding red ring. Being so close to the trigger and functional from either side makes the safety catch easy and fast to use; just what a CQB menace like the M870 Tactical needs!
Up top, we are treated to a 20mm Picatinny rail, a nice feature for modernising your close quarters setup with the use of a red dot optic. We recommend the AIM-O SRO Styled Airsoft Red Dot Sight for a unique combat-optimised look!
At the rear, we come to the semi- pistol grip and stock, which is constructed from polymer. The grip is comfortable to wield and features checkering on either side for superb gripping qualities. On the bottom of the stock, we are treated to a Harris-style sling/bipod lug; while you may not be mounting a bipod here, a two-point sling is the ideal addition when combined with the Harris lug on the shell cap. You have the choice of adding a Harris-style sling swivel, using a reinforced keyring or loop of paracord to mount your sling, though we recommend paracord to prevent battle rattle.
The removable gas tank is stored inside the stock and is removable after removing the butt plate. To do this, squeeze both sides of the butt plate, pop it off, then you have access to the gas tank section. With the gas tank removed, you’ll find the fill valve on the front. We recommend standard pressure green gas in warm weather and red gas for sub-10 ° ambient temperatures.
If you've ever wanted to blast first and ask questions later in CQB, the Tokyo Marui M870 Tactical Gas Airsoft Shotgun is the perfect thing. A fantastic quality full metal build with 3 or 6 BBs per trigger pull and a ferocious yet modern aesthetic, this beast of a shotgun is as iconic as it is formidable!

Joule Charts
Special Instructions
These tables can be used as a reference to see if the BB weight you are using will be over acceptable joule limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used at Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
