Welcome to Homebuild History, a new segment on 3D Gun Builderโs website where we focus on the history of some of the most iconic homebuilt firearms, their contributions to the world, and most importantly, how YOU AT HOME can get your hands on these classic arms and armaments!
Whatโs the Story?
The year is 1942. World War II is in full swing in the Pacific Theater and the Philippines have fallen. MacArthurโs claim he โshall returnโ is weighing on the back of everyoneโs mind, not just for the Filipinos whose sovereignty has come into question, but also the remaining Americans whoโve refused to go down without a fight.

The arms and ammunition the Americans had been fighting with since the initial invasion began are running low, and getting spare parts from abroad is no longer an option. So it was that the Filipinos turned to local ingenuity above all other things to keep themselves armed in the face of occupation โ and the paliuntod was born.

An incredibly simple and crude weapon, the paliuntodโs known as the pipe gun for a reason: thatโs essentially what it is. Paliuntods in their crudest form are two lengths of pipe, one slid inside the other, with a shotgun shell or other projectile retained inside the smaller pipe. The shooter needs only slam that pipe back into the firing pin fixed at the back of the larger pipe to fire the weapon, hence the term โslamfire.โ
During World War II, the paliuntod became part of the bread and butter of the Filipino resistance, used by American servicemen and local guerrillas respectively. As a single shot weapon, the intent behind their use was to ambush better-armed Japanese patrols or guards, kill them, and strip them of whatever guns, ammunition, and useful goods they possessed. While a small part of the war effort in the worldโs biggest ocean, the paliuntod was enough to help keep the guerrillas alive and ready to aid MacArthur in his valiant return.
It was after the conflict ended that a crude weapon of war became a means of refining metal into money.
All-American Insurgency
Iliff D. โRichโ Richardson, fresh off his stint as an American soldier fighting against the Nipponese war machine, thought that there would be a market in America for insurgency-grade weaponry. With a glut of manufacturing left over after World War II, it wouldnโt be long before a commercial replica of the paliuntod heโd used in the Pacific came to the US market at a smooth $7 price point.
There were multiple versions. Some were as crude as the guns disposed of by guerrillas, just tubes screwed to a wooden stock. Others were โdeluxeโ models with manual โsafetyโ triggers and vertical foregrips to make firing them easier and less likely to accidentally take out an eye. While a creative and innovative firearm for the 1940s, the R5 simply couldnโt match the prices of surplus GI shotguns. With everything from Winchester 1897s to Ithaca 37s flooding the market, there was no way that even at bottom-dollar prices the R5 could have an edge. The limited run of guns in their various variants are now valuable collector items, worth dozens of times their original retail price.
War to Peace to Crime
The simplicity of the paliuntodโs design meant that inevitably, it began to be fabricated by criminal elements in the Philippines. The rebel groups that ended up fighting the Marcos family used them. So have communists, jihadists, and local self-defense forces in the eighty-plus years since the earliest examples were made.
Because of how simple the design is, the paliuntod has been built and modified more than a 1960s roadster. The hammergun seen above isnโt the craziest variation of the design. Double-barrel paliuntods have been made by, and broken the shoulders of, several people in Latin America. Some paliuntods have all the options. Shell holders. Vertical foregrips. โCookie cutterโ pistol grips similar to the Sten submachine gun. Trigger โsafetiesโ to keep the gun from accidentally slamfiring. Even underbarrel flashlights for โtacticalโ night operation โ the sky really is the limit.
In the United States, where firearms are arm-in-arm with the world of hobbyists and DIY, and 3D gun builders have made companies like Creality and eSun hundreds of thousands in printer and filament sales, the paliuntod design makes money in another way โ an easy build for grifting gun buybacks. The total cost to make a working example is the price of a dinner at Olive Garden, if not less. Considering how much in the way of cash cities are shilling out for anything considered a shotgun, people have made hefty three-to-four-figure profits building and turning in paliuntods in exchange for prepaid gift cards worth significantly more than the guns themselves.
Technically, everyone wins with a paliuntod: the builders get paid. The anti-gunners at Everytown and Giffords get to pad their numbers with a bunch of โseized firearms.โ Best of all, the police get to cringe at how stupid their city government bosses are for wasting taxpayer money. These buybacks are obviously ineffective in stopping criminals from possessing guns illegally. The homebuilt gun communityโs also fortunate enough to get plenty of quality memes out of every sale.
How do I make it?
Now that basics are out of the way, what will you need to make one at home*? Well, take a look at infamous ultrasurvivalist Kurt Saxonโs instructions for making an example from a couple of decades back. Countless sources of media both written and filmed have explained how to build these things. A child can make one โ theyโre that easy to fabricate. Kurtโs writing, however, is clear, concise, and can fit into a single picture.
Youโll need 6 parts: a nail, a 1in dowel, some thin cardboard, a 1in metal pipe cap, some 1in threaded pipe, and some 3/4in pipe. The nailโs driven through the cap and cardboard, then cut down to size. The tipโs cut and blunted just enough to not pierce the primer when the gunโs fired. The โstriker assemblyโ is epoxied into the cap, which gets screwed onto the 1in pipe. A shotshell gets placed into the end of the 3/4in pipe and stuck shell-first into the 1in pipe. After that, the weaponโs locked and loaded. Slam the 3/4in pipe into the 1in pipe, and kaboom. The pellets or slug are then sent flying downrange, probably missing whatever you want to hit past 5-10 feet.
Sadly, the days of churning out paliuntods at a $5-7 price point are long gone. That said, you can still, with a bit of frugal searching, make them for anywhere from $20-30. Theyโre probably some of the easiest guns to build. If you live in a buyback state, theyโre certainly the easiest to turn into some serious cash.
