Dude Makes A Soda Can AR-15!

In one of the most awesome feats I have seen on YouTube in a while, YouTuber FarmCraft101 makes an AR-15 lower receiver from old soda cans. That’s right, a soda can AR-15!

All of you pedantic jackwagons out there that get pissy when someone says that they ‘built’ an AR-15 can shut your wordhole this time. If anyone should be able to claim that they built their own rifle, it is this dude.

If anyone should be able to claim that they built their own rifle, it is this dude.

FarmCraft101 starts out with a bunch of aluminum cans, melts them into ingots, then builds a mold to make a 0% receiver. Using a mill he transforms a chunk of metal into a sort of recognizable AR lower that I would be proud to own for no other reason than the pure novelty of it.

To top it all off, he polishes the piss out of the receiver, gives it a serial number, then assembles an off the shelf rifle kit around his homemade lower receiver that it presumably made from old Coca-Cola and Pabst Blue Ribbon cans.

FarmCraft101’s badassery doesn’t stop there, he does all kinds of other cool crap on his channel like take a 1″ piece of rebar and turns it into a giant bolt for no other reason than because he can. He also built a copper rose out of old plumbing pipe so he could presumably a lady with his badass skills (He could have charmed the pants off of Mother Teresa with that rose. It is pretty freakin’ cool.)

Check out his channel for more cool videos, but mostly watch the one I posted below of him building his soda can AR-15.

    Surprised he didnt just sand cast it. Probably would have been easier.

    Point of clarification: As a guy who builds machine stuff for a living, my gripe isn’t mere pedantic jackwagonry (though I may be a jackwagon), it’s righteous indignation at the idea of an assembler of parts calling themselves a builder.

    Kind of how I feel about certain people saying “yes, Biff and I just built a new house.”

    You didn’t build crap. You paid people to build it for you.

    • Jeremy Star

      So technically a person who builds a house isn’t even a builder in your opinion, since he didn’t cut the tree and make the wood planks himself, mix and set the drywall material into planks, etc; He just assembles the parts.

    • Sam Damiano

      An assembler is a builder, a maker would make parts. Someone who pays someone to build something is a customer.

    • iksnilol

      There are people that do that?

      I use engine/motor and clip/magazine interchangeably. Come at me.

    • Edeco

      It sounds like you don’t make your own billet. We’re all links in the great chain of industry. Bringing together parts and labor is my way of building 😛

      • Herp

        I turn coarse ore into concentrate.

        Am I a builder, or did the miners build the ore?

        • Edeco

          Both. Well, mindless celestial and geological processes may have built the in-situ ore. But they are under the yolk of a higher power now; that of thinking men. *hubris, hubris*

    I couldn’t stop watching. Thanks for posting.

  • jcobbers

    I saw this on youtube yesterday and it made me realize how awesome home grown machinists are. This kinda intellect and skill is what makes America awesome. Home made freedom baby! Plus he’s recycling, and that’s good for the environment, so environmentalist should be happy, it’s a win on all sides.

    • GaryOlson

      This makes me nostalgic for the work I used to do all day every day…..a couple decades ago. Before NAFTA…..

      I wish I had a guy like this as my neighbor. All mine are tweakers and drunken NFL fans.

  • marinepride

    I do not regret watching this

  • Haulin’ Oats

    So if the can15 was made from cans, then was the car15 made from cars?

    • DW

      Colt used to be a part of Cadillac group. Coincidence?

  • lowell houser

    Saw this the other day.. damn. I had honestly been planning this and he beat me to it… BUT I had been planning on trying a 3D printed lost-PLA casting instead of going the traditional greensand route because that’s just a whole lot of unnecessary work. SO I can still be first at that.

    • gene

      If you do it, video and post it. That’d be neat to see.

  • pbla4024

    Wouldn’t it be better to use lost wax casting method? Was it tried?

    • Twilight sparkle

      There was an old post on arfcom back when arfcom was good (or rather less annoying) about a guy who was trying to do a lost wax cast with aluminum cans of an ar-15, the shrinkage was too much of a problem for that method iirc

      • Xanderbach

        You print at 110%. Not that hard.

  • Kurt Akemann

    Recycling FTW!

  • Jay Ross

    Looked into melting soda cans down for other projects and some machinist forum mentioned that cans wouldn’t be their first choice for scrap. The alloy isn’t the best at being machined and it’s dirty from the lacquer they put on the inside to keep the acid from reacting with the aluminum.

    • iksnilol

      But an AR receiver is pretty low wear component. I mean, they’ve built them from Lego or wood.

      • Jay Ross

        I think it’s more to how cleanly it takes to being cut. As for it being dirty, there’s so much metal and it’s such a low impact part it probably won’t matter.

        • Precious Mettle

          Nothing to do with machining, it has to do with the casting process.

          Aluminium alloys used for casting typically contain a high silicon content – 3-15% – this makes the alloy flow and fill out the mold better, making the casting process easier.

          Aluminium alloys used for drawing and extrusion (like the alloy a can would be made of, usually 3000 series alloys) don’t contain as much silicon (<0.5%) as the cold working properties of such an alloy are more important to the application, and the silicon microstructure in the alloy is highly abrasive and would wear out the tooling faster.

          Any of the lacquer, printing, or anodizing on the cans would be more than obliterated by the smelting process and simply turned into dross – but that's another issue with casting cans; per weight, they are particularly low yield. High surface area but low volume means you lose a lot of the weight of the can you melt to dross, rather than usable aluminium.

          There's nothing wrong with machining an ingot of 'coke can' aluminium, it does suck because it's gummy, though it's perfectly workable. But there's lots of reasons why you wouldn't want to cast a lower out of it.

          • gene

            But sometimes “can do” is more important than “should do”. Points are noted, but the journey was really neat.

    • Edeco

      With the high surface area and polymer film I’m surprised, any way I could think to do it at home I’d expect most to burn away and/or into slag.

    • True cans aren’t ideal for casting, but it’s the CHALLENGE! For me, there was something alluring about going from a common piece of household garbage, rather than cutting up old cast wheels or auto parts. I think it adds to the build, and it is strong enough to serve it’s purpose.

  • therealgreenplease

    I love the home-built firearms. Keep it coming TFB!

  • FightFireJay

    But he didn’t injection mold the handguards, he didn’t make the mill, he didn’t mine the bauxite ore for aluminum….

    • I know, I feel like I was cheating taking already smelted aluminum scrap. 😉

  • Cymond

    “He also built a copper rose out of old plumbing pipe so he could presumably a lady with his badass skills”

    Wait, WHAT does want to do to her?

    • Timmah_timmah

      A few typos but I just plowed through it haha

      • law-abiding-citizen

        That’s what she said when dude gave her that copper-pipe rose . . . “Just plow right through!”

  • Guns from scrap

  • Mr.SATism

    So, um, did he just make a ghost gun?

    • Technically yes, but it’s legal to make your own for personal use. I won’t be selling it though.

      • Mr.SATism

        That’s very good to hear, I loved seeing your build, it felt very innovative!

    • law-abiding-citizen

      No, because I don’t believe he included the 30-caliber magazine clip, nor the ability to fire it (whatever the hell it is) in half a second . . .

  • 22winmag

    Pathetic jackwagons?

    This once fine blog is starting to read and feel more like ttag everyday.

    • Twilight sparkle

      Not going to name names but I’ve noticed it more from certain authors…

  • Was this written by Time-Traveling College Freshman Patrick?

  • Ryfyle

    Soda cans are made fro ma 2XXX series Aluminum alloy. For anything heavier duty I would suggest a pinch of magnesium, no silicon though.

  • Robert Kruckman


  • Ed Forney

    All it takes is $400,000 worth of tools.

    • Actually that’s a $2500 Grizzly mill that I just recently bought. The lathe is another $3000, but you could do this build without a lathe if you had the right sized tap. Not as pricey as people think.

      • Ed Forney

        I just missed it by just two zeros !

    Honestly, you could probably an entire stripped lower using lost wax technique using a styrofoam form.

    Will this lower hold up to being hit with a hammer ?

    Ever since some wisecracker on some forum years ago said “the army just wanted rifles they could make out of old beer cans” I have wanted to see this done, my life is now complete.

    • law-abiding-citizen

      But back when that was said, beer cans were made of steel . . .

  • Wrex

    I’m surprised that people are surprised and just now learning about doing this, actually. Lol.
    But I am glad that they are. Also good to learn alternate ways of making things, just ’cause.

  • Robert Kruckman

    VERY COOL!!! I always wanted to have machinist skills cause I love working with my hands and still do. But I became a COP cause better pension!!

  • Seth Hill

    I have a bunch of cans that I had contemplated melting down to ingots to take to recyclers. I wondered if they could be used to make a lower. Aluminum cans are typically made of 3004 or 3104 aluminum, so I am curious what the long term durability of this lower is.

  • John

    Let us know when he actually uses cans instead if molten aluminium.
