How to Build an Airsoft Artillery Piece

This is an instructional bit on how to make airsoft games more war-like by adding an artillery piece to the mix. I promise you it's very simple, not too expensive, and a whole lot of fun.

    Make a base block. Use a good, strong piece of wood about 2 feet (0.6 m) by 2 feet (0.6 m). This will be what everything else is built on.

    Get a 2 by 4 approximately 4–5 feet (1.2–1.5 m) long. Attach this to the top center of the 2 by 2 foot board with the end of the 2 by 4 matching up with the opposite side of the board so now it sticks out. This will be the boom that controls the aim of the piece.

    Now, attach two 6" diameter wheels that do not swivel to the underside of the piece. You can get them at any home improvement store, but make sure they're the ones that come pre-assembled so that you can just screw them on. (I drilled pilot holes first and then used a screwdriver.)

    Use two 4 by 4 inch blocks of wood about 6–8 inches (15.2–20.3 cm) long to attach to the 2 by 4 you already put on the board. Make sure they are both on the 2 by 4. When you look down the barrel of your artillery piece, they should be in line with each other because they are going to be the things holding the barrel up.

    Put a 2 by 4 about 2–3 feet (0.6–0.9 m) long along the tops of the 4 by 4 blocks. This will be what your barrel sits on top of.

    Now for the barrel. A THICK PVC tube anywhere between 4 to 6 feet (1.2 to 1.8 m) long is required at about 2-2 1/2 inches in internal diameter (caliber, really.) If the barrel is not thick, the barrel may melt and deform.

    Do not attach the barrel with screws or nails. Instead, use string and wrap it around the barrel and the 2 by 4 it's laying on. This, or you could use brackets, but string is easier, simpler, and less expensive. Really any thing that does not interfere with the inside of the barrel could be accepted.

    Build a chickenplate. You may be wondering how you're going to be protected from incoming fire. The answer: build a chickenplate. They are often used on the tops of Humvees to protect the gunner from incoming rounds. Yours could either be made from cardboard or wood. Cardboard is more fair, but I would recommend wood because it holds up better to the elements. Make sure it's something light, like pine, or it'll be too heavy to move around. Get yourself a nice big sheet and cut it down to the size you think is suitable. Remember, this is what's saving yourself from going "out" in a firefight.

    Get some "shells." Soda bottles work perfectly for this role. Anything under 20 oz should just fit right in the breach. Don't use water bottles because they are too flimsy. Get about 6 "shells." You will need them.

    Personalize it. Put your team emblem or name on it. You could add a holster to your side of the Chicken Plate just in case, or even cut a hole in the chicken plate and mount a high capacity AEG (Like a cheap $30 P-90) for use as an "MG" so you can rain down fire on a location in two ways. It's up to you, make it what you think is best for your situation.

    If and only if you live in states that allow them, you can use bottle rockets, put them in the bottles, have a buddy light them, and shove them in the breach. I would recommend the tiny ones that whistle and pop for a flashbang effect without the flash. Those deafen the people it detonates next to and could cause them to be combat ineffective for a few seconds while somebody runs for cover or to a flanking maneuver. Bottle rockets do very little in shrapnel damage, but should still never be pointed intentionally at the enemy, just near them is enough.
    • Another suggestion for ammunition is roman candles. Stick them in the bottles and tape where the stick part comes out so it does not fall out of the bottle. These have some kick and do not stop firing until they are completely done, so make sure you push it securely into the breach, even up the barrel a bit. Either that, or tape it. Trust me, you do not want one blasting its way out of the breach and exploding behind the piece. They can burn quite a bit if one of the balls hit you. Again, this is an area-effect weapon, not to be used for direct fire. Shoot above or to the sides of your intended target so you don't leave your enemy with burns.


  • A good rate of fire for rockets is 6-10 rpm, a good rate of fire for roman candles has yet to be determined but might be somewhere around 2-5 rpm depending on what kind of ordinance you use.
  • A good fire team consists of 4 people. 1 gunner, who loads the breach with the shell and then unloads it. He/she is responsible for physically aiming the gun as well as using the MG. 1 loader, who loads the empty shells with rockets or roman candles. He/she is also responsible for guarding the close perimeter of the piece with a handgun or other compact weapon if the flank security is compromised. 2 flank security personnel, who watch and defend the flanks of the piece to prevent the gunner and loader from being compromised. They are armed with AEGs and sidearms and are also responsible for bringing ammunition to the loader, though at least one of them should always stay with the piece and its operators to protect it.
  • To better utilize the two man operating team, the gunner should hold the shell partway into the breach so that the loader can light it. Then the gunner can ram the shell into the breach and use the MG until the loader prepares another shell in a few seconds.


  • DO NOT use illegal fireworks if they are illegal in your state. Many states have laws about fireworks, and though many states allow these things, it's important to know where you stand.
  • DO NOT use fireworks other than those recommended. Doing so could potentially harm the device, you, someone's property, or someone else.
  • DO NOT use to hit structures or in fire-prone areas. This could cause serious property damage.
  • ALWAYS wear eye protection when playing Airsoft as well as using this device.
  • NEVER use this device to intentionally harm someone. It should be used by trained and responsible people only.
  • ALWAYS use this device for indirect fire over the enemy's head or somewhere else that the enemy is not physically occupying.
