How to make C4 with RDX explosives

In this article we’ll review how to make C4 with RDX, RDX is the primary ingredient for making C4. RDX (Cyclotrimethylenetrinitramine) is a nitroamine (organic) high explosive. In its purest state, RDX is a white, crystalline solid, and when mixed with plasticizers and other ingredients it makes C4. RDX can be stably stored and is considered one of the most powerful explosives used by the military. One of the most alluring factors presented by RDX for military application is RDX requires a detonator, is resistant to detonation by small arms fire, and is 1.5 times more powerful than TNT (Trinitrotoluene).

RDX MoleculeA word of caution to all our readers, every article written by usCrow contributors is either from personal experience or extensive research, and we make every effort to ensure each article is factually sound. Do not assume reading one How to Make C4 article qualifies you to start Breaking Bad in your kitchen with Skyler White’s cake mixer. In fact, if you try to make this stuff in the presence of government, you’ll end up in federal prison…

Is C4 illegal?

Whether or not C4 is illegal is totally dependent upon the stated purpose of its use by you. If you want to tell the government you need C4 to protect your fortified prepper bunker in preparation for the apocalypse, they’ll say no. To legally own C4 you will need a Destructive Device Permit (kind of like an NFA regulated firearm permit), and it must be approved by the BATFE (Bureau of Alcohol, Tobacco, Firearms, and Explosives), and your County Sheriff’s office. For all intents and purposes, other than commercial, it is illegal for you to own C4. You have been warned…do not make this shit until after SHTF.

High Order Explosives

High order explosives are pretty easy to make when used with a basic understanding in chemistry, aside from the nitric acid used in high explosives. High explosives generally detonate because their molecular structure is made with fuel and three or more nitrogen dioxide molecules e.g. TNT (trinitrotoluene) – when a shock passes through a trinitrotoluene molecule the NO2 bond is broken, and oxygen combines with fuel.

How to Make C4 with RDX

Unlike other high explosives you can make RDX with this simple method, with the exception of the ammonium nitrate. All necessary precautions should be taken to prevent injury or death. Below I’ll list the equipment and materials you’ll need to make RDX. To purchase online just click each item.

Materials need to make RDX

How to make RDX

  1. Place beaker in ice bath and carefully pour 550 ml of concentrated nitric acid into beaker.
  2. When acid cools to 20 degrees below centigrade, add small (pea sized) amounts of crushed hexamine tablets into the beaker.
  3. The temperature will rise after adding the hexamine; continue to slowly stir the mixture with your glass stirring rod.
  4. Do not let the mixture go above 30 degree centigrade or you’re fucked. Add ammonium nitrate to the liquid bath to cool it down faster.
  5. Add more ice and salt into the ice bath to bring the temperature of the mixture to below 0 degrees centigrade. Maintain the temperature for twenty minutes (set timer)
  6. Pour mixture into a liter of crushed ice, shake and stir mixture like a martini.
  7. Allow the mixture to melt, once melted use your funnel and filter paper to extract the crystals while disposing of the corrosive liquid left over.
  8. Bring a half liter of distilled water to a steady boil and add the crystals.
  9. Immediately filter the crystals out again and test with blue litmus paper (you want it to stay blue), repeat steps 8 & 9 and the blue litmus paper stays blue.
  10. Allow RDX crystals to be thoroughly dried before storage.

How to make C1 and C4

You may opt to make C-1 which is a bit easier to make than C-4. C-1 is made by using 88.3% RDX, 11.1% mineral oil, and 0.6% lecithin by weight. Kneed these materials together in a plastic bag to desensitize the explosive

C4 can be made with the same technique while substituting materials such as; 91% RDX, 5.3 dioctyl sebacate as the plasticizer, 2.1% polyisobutylene (or synthetic rubber) as the binding agent, and 1/6% mineral oil.

In closing…

As with many of our other articles you take on all risks, and hold harmless for any damage to property, injuries, or loss of life. By no means are you to attempt to make this without proper training, and permits. This guide is solely meant for use after TEOTWAWKI (the end of the world as we know it). Furthermore, as we’ve seen in our Tannerite, and Thermite articles, the comments section is a wealth of additional information. If you have any extra input, feel free to comment below.

  1. lots of smart men,figure this one out. all goverments as we know them make money constanly and lend it on intress but no goverment has ever made the intress,,,we dont make the intress its ilegal,,when all this worns out thats the end of goverments as we know them

  2. what happen if i dont do this work i will die?according to the passage that say Do not let the mixture go above 30 degree centigrade or you’re fucked.

  3. i will kill 30 portage central high school kids i will kill nigers i will kill police officer shermack the military assault rifle i will use is a AK 47 i will wear a black mask and civilian clothing i will carry 2 m67 hand grenades i will put on 4 military mag holders i live in portag MI

  4. i will kill 30 portage central high school kids i will kill nigers i will kill police officer shermack i will join isis the terrorist group

    • Kill yourself or stop your hate. hate is why we are where we are. I dont hate bigots i love themand feel deep deep sorrow for them. Children are not only inocent but also the future. Why talk if what your saying has nothing to do with the above. Hate has clouded your brain from reality. The reality is that there are people with unlimited money supplys and support who hate all of us white black green stupid smart angry happy. They do not care. We are all we have. Also i feel your either a child with a low iq or one of the trolls they have supporting them. If your a supporter people will kill you. There is a revolution coming. And it will be led with hope love vengance and blood. I would rather have you die so take all that shit to your closest federal reserve world bank irs building courthouse jail or gov building before you kill a kid. Because we are done with this stupidity. So you can shut the f up and kill yourself if your a troll and if not then you need to review your reality if your a real person. Im sorry you have lost faith in the people. But its not their fault its the lies brainwashing and chemicals the 1% feeds them they know not what they do. As for you if you can not practice love then get a little mental help.

      • very well said my fellow fed up with large govt. brother…hope to have you fighting by my side when cleansing comes

  5. Don’t make until after SHTF but it’s hard enough to find the chemicals now, come the apocalypse it’s not like you will find these chemicals or be able to order on Amazon. I also wonder if the FBI would show up before your package.

    • i want to join a militia i want a spec ops buy cut bag i want a armor plate vest i want a gi mre food 10 pack i want a russian military gas mask i want a assault rifle i want 32 m67 hand grenades i want c4 i want to kill 90 portage central high school kids i will rape 2 high school girls

      • You dude…bet your Ass,if you think I’ll allies your coward Ass to even attempt that,I’ll come down on your punk Ass like the g Ass .net of God if you want to have a fight….come find ME and I’ll end your bitch Ass instantly.Get off this page and stay!!##my name’s the Reaper,if you need anything adjustment to your brain…I’ll be happy to do it.

  6. Before making/handling HE wash and dry your clothes with extra anti-static chems that your wife uses for laundry. Also spray the bottom of your shoes and wipe your hands with it….or die. Especially in winter.

  7. Heard the Q about Concentrated Nitric Acid. There IS a difference between common Nitric (HNO3 @ 70%) and Fuming/Red Nitric Acid. I have seen a recipe where the fuming Nitric was used in this same process. If so, it is easy to make. Simply place about 30 grams Potassium Nitrate in the 500 ml Retort and add 200 or bit more of Sulfuric Acid(Conc). Heat until red fumes appear and keep that temp as the fumes condense in the Retort’s tube. Collect and keep cool to reduce fumes…they are TOXIC!!!!!!!! Use as you would reg Conc HNO3. I am not sure if the fuming Nitric is what is meant in these instructions?

  8. Nice article on RDX. C-1 is a yes sincalternative.e the other plasticisers are difficult to obtain and definitely raise eyebrows. YES u must wait for SHTF!!!!! I had scholarship in Chem Eng. and we often used ethyl alcohol added to the ice mixture to quickly lower the temp. Better than the alternative.

    • LIKE I said Make it and sell me some I will not try to make it I am not smart but smart enough not to mess with this lol.

  9. We’re rubber gloves wile handling c4 for sure, if your body absorbs it it will give you the shits

  10. Better recheck your step 2 instructions Brah. An ice water bath will get you to 0 degrees Centigrade but you won’t get to -20 degrees C. You probably wanted the ammonium salt and table salt in there in step 1?

    Easy conversion method for temperature from Centigrade to Fahrenheit: 1.8 times C plus 32.

    0 degrees Centigrade is 32 degrees F (ice is 32F). Boiling water is 100 degrees C ( aka 212 Fahrenheit).

    • no if you put water inside a glass container and pump out the remaining air it will start to boil cold

      • i will kill 80 portage high school kids i will use a assault rifle i will use 2 m67 hand grenades i willl make c4 and i will blow up the high school i will kill police officer shermack the terrorist threat is real

  11. Y’all have neat videos of blowing sh¡T up?
    P.s. what happens if it reaches 30degrees? You mentioned I’d beith phlucked. Do I just go boom?
    Or is it like a Molotov?

  12. Concentrated Nitric Acid ph is 70% or 100%?
    I don’t know average Concetrated Nitric Acid PH

    • PH is on a scale of 1-14, you’re talking about concentration, easy mistake to make but its worth reading up on.

    • Cool and dry, really. But not that badly important compared to, say, TNT, since it won’t explode through fire unless its industrial-furnace temperatures. It needs to be detonated, not just burned.

    • Keep it cool, dry and I would recommend out of sunlight. If made properly it can store for years but, keep in mind that what you make at home is not military grade. The longer it sits, the more unstable it becomes.

    • You want to break the tablet into pea sized. Then crush tablet and continue with process. Let me know how it progresses.

      • i will kill 30 portage high school kids i will join isis the terrorist group i will kill police officer shermack

        • Your a dumbass. Its idiots like you that need to be given the slightest of disinformation so as you kill yourself and not others, Asshole

    • Wikipedia lists 10 Nitric Acid to 1 Hexamine but that’s by mole not volume so…

      Never done this experiment myself because I’m at a good place in my life and am not really looking to add any death or prison right now but, from a purely theoretical perspective, I would imagine that, as the hexamine is added, it dissolves into the acid as the chemicals react. If so, it should be fairly easy to observe when the hexamine stops dissolving into the solution – kind of like when sugar stops dissolving into sweet tea after it becomes saturated. This would be your indicator that the nitric acid was used up. Adding more hex would be futile and would only cause you headaches in the remaining processes of filtering and washing the RDX out of solution.
