Haw San “Mad Max” double barrel shotgun

I always wanted to have a true shotgun for airsoft, but not something that only looks like one, but also shoots as expected. Unfortunately, each time I asked someone on the field about theirs, the answer was always the same “it looks nice, but shoots only 1 bb at a time”.

The closest thing to my expectations was a gas propelled, Tanaka M870 shooting 6 bb’s at once. But I had two problems with it: the smaller problem, was it’s size – the idea was to carry it as a secondary to my sniper rifle, to have something to shoot in CQB situations. And the bigger problem was the shell ejecting mechanism. A pack of 5 shells costs around 75$, so loosing them in the heat of  battle due to ejecting the shell in some odd place, was a big turn-off.

And that’s where the Haw San “Mad Max” Double Barrel Shotgun comes in. I found it by a complete accident, mentioned in a topic about a completely different replica, and fell in love the moment i saw it. I have searched a lot of sites looking to buy one, but it was sold-out, almost everywhere… almost… 🙂



The replica comes in a standard grey box, with no markings of what’s inside. The only thing You will find outside is “Made in Taiwan”, and “GR-6801” printed on the side.




After opening the box, You will find a set of paper targets, and a mini manual.


First Impressions:

The replica itself is held by a thin molded plastic, with a clear plastic cover, under which You can see the shotgun, two shells, and some poor quality bb’s.


The shotgun was imported form the US, hence the ugly orange tips.


I proceeded to remove them (reading somewhere that You can just pull them out), but unfortunately mine were glued in, so taking them out, did some damage to the rubber caps.


The replica feels very solid, and heavy, due to the weight being distributed mainly in the front, with a short grip, especially when  held in one hand. There is no wobbling, or any other unwanted part movement – everything is well put together an secured with screws – it feels like a really high quality product. It has an unusual design with two triggers – one for each barrel.

The wood used in the shotgun is called Amazakoe (Other names: Amazakoue, Amazoue, Shedua, Ovangkol), it’s a high quality heavy wood from Western Africa, it’s oily and hard,  so staining can be problematic (if You want to change the color of course). All I can say is that the wooden parts are well finished.

The metal, apart from the screws, and inner barrels, is most probably ZnAl, as it exhibits no magnetic properties. Which is a bit disappointing after high expectations set by the wood.




It’s a break action shotgun, so to open it, You will have to move the lever to the right, and push the barrels down, or just swing it forward, and it will open by itself. When the lever is released, it returns to the middle position.


A very welcomed addition is a part that pushes out the shells when the shotgun is opened, it helps a lot with fast reloading.




When You look down the barrels, You will notice that inside are two (each for one barrel) inner barrels. They are held in place by some thick rubber mounting pieces. It’s designed so that the “lip” of the shell goes in to a groove in the rubber piece, that centers the shell with the inner barrel.



Shells are made from aluminum, and hold 7 bb’s each. The loading is quite easy, just pull the blue part, and the shell will break in two pieces, one for holding the BB’s, and the other to load with green gas.


The shooting mechanism is quite straight forward. Trigger when pulled, pushes an arm, that in following pushes out a small pin, that opens a valve in the shell.





Well, what can I say, it’s great to clear rooms, and small spaces. The range is between 25-30 meters, with 0.2 BB’s and standard green gas. The spread of BB’s at those 30 meters is 1.5 meter on average. I must say that I have expected a lot more spread, but thanks to those two inner barrels the accuracy is quite impressive.


Basic disassembly:

On the bottom of the front grip You will find a small latch, pulling it will let You remove the grip, from the barrels.








After that just break-open the shotgun, and the barrels will come off.



To remove the inner barrels, You will have to unscrew two little screws found in the front, on the bottom of the outer barrels.




Next pull the rubber caps, and push on the inner barrel, so it comes out on the other side (where You put in the shells) with the second rubber mounting piece.



(now the shotgun will look a lot better:)





Unscrewing, and removing the two uppers screws(next to the lever), lets You take off the wooden grip, and reveal the trigger mechanism.




To separate the wood in the front grip from the rest, You will have to unscrew 1 wood screw in the back, and two small screws from the latch.



Shells from different shotguns:

So a lot of people are asking if they can use shells from other manufacturers, like Tanaka M870 and Goblin ones. And the answer is Yes, but after some modifications:


Tanaka M870 Shells, are smaller in diameter and fall inside the outer barrel. They need a thick o-ring near the shells collar, that will keep them in place, and some kind of a thin pipe to decrease the inner diameter of the shotguns barrel.

As for the Goblin shells, they also have a smaller diameter, but the collar is the same as the original shells, so to use those You will have to increase the shells outer diameter, or decrease the shotgun barrels inner diameter. Apart from that, the goblin shells have 4 BB holes instead of a one in the center, so to use them You will have to completely remove the inner barrels.


Conclusion: Great shotgun, excellent for clearing rooms/tight spaces, and has a lot of potential (custom shells etc). The break-open action, brings joy with every reload 🙂

– No wobbling
– Made of real wood and metal (probably ZnAl, but still better than plastic 🙂 )
– 7 BB’s per barrel (on standard shells/12 on Goblin)
– Heavy

– Shells are quite expensive
– Lack of spare parts
– Black paint that will scratch easily
– Heavy


  • Great review! I’ve read a couple of others but noone says what kind of wood or metal it has, thanks for that. Will probably get one if I find it discouted a bit.

    BTW. What is the manufacturer? Some say KJW, others Haw San?


  • Hi Jake!

    Unfortunately I have no way of checking who the real manufacturer is – when I bought it, it was labeled as an KJW product, but there are no markings on the box, manual or the replica itself apart from the “Made in Taiwan, Haw San Toys” on the side 🙁
