How to make C4 with RDX

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.

Equipment needed to Make RDX
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.



How to Make Ballistic Plates for Body Armor

Body Armor and Ballistic Plates should be standard PPE (In accordance to MOPP Standards) for your team. The presence of hostile elements in all disasters (man-made or natural) is an eternal truth. Having access to these plates will make the difference between life and death. Ideally, you want standalone ballistic plates that can be used in conjunction with a plate carrier instead of a bulletproof vest. The most basic and user-friendly way to achieve this is with heavy steel plates that have been improved.

Typically, people tend to ‘make’ stand-alone steel ballistic plates that are nothing more than a 10″ x 12″ x .25″ piece of steel. While these steel plates are capable of stopping .223/5.56 ammunition, they are very heavy. A .25″ steel ballistic plate’s average weight is 8 lbs.

Ballistic plates can vary from what size round you intend it to withstand and how much weight you can carry. Most ballistic plate carriers hold four plates; front plate that protects vital organs, rear plate that protects your spine and vital organs, and two side plates. There are several different options in ballistic plate ranging from polyethylene, ceramic and steel which I will be covering in future articles.

How to make Level III Ballistic Plates

A Level III Plate refers to rifle protection. For a ballistic plate to be considered Level III it must be properly tested. Test your plates in the field by firing 6+ rounds of 306 FMJ and NATO 7.62 x 51 mm. If there is no penetration by these rounds you have a standard Level III Plate. Testing is vital, zero penetration is the goal.

First of all you will need a ballistic plate carrier and the measurements on the pouch that holds your plates. You can usually find good deals on Amazon for Ballistic Plate Carriers. A common size for a standard plate carrier is between a 10″ and 12″ plate. If you choose to take an alternate route and use a modified tactical plate carrier with your own custom sized pouches then make sure to take measurements of the size plate you will need.

To effectively make an efficient plate you will need some source of heat to bend and temper your plate i.e. torch. Also I prefer a wet saw for cutting your plate to size, and you will need welding gloves or clamps to hold your material i.e. used motor oil.

Before I begin the process of making your ballistic plates I would recommend using at least a 3/8″ plate which can withstand most 7.62 rounds.

After you have the correct size of your plate and cut your material to size you will need to heat your plate. Using a torch you want heat your material evenly till you see your plate glowing red-hot. Do Not hold your torch in one place too long or you will burn a hole through the plate. Once you have your plate heated I suggest clamping it to a work bench to add a slight curve to the plate. If done correctly your plate should sit level on a table and your highest point in the center should only be about 3/16″ high.

Now Its time to temper your plate which is also referred to as hardening steel and this is where the used motor oil comes in to play. Take your used motor oil and pour it into a bucket preferably metal so you don’t burn holes through a plastic one unless you have steady hands.  You will need enough oil to completely submerge your plate. Once again you will need that heating source. Heat your plate evenly till it glows, then submerge your hot plate into the motor oil. The reason behind using used motor oil is the carbon deposits in used motor oil. As most know, metal expands under heat due to the molecules separating when submerged into motor oil. The carbon deposits fill in the spaces that the heat caused, making hardened steel.

Now you can clean off your plates and place them in the pouch of your vest, but as I said earlier this will stop small arm and most 7.62 rounds. However, there are a couple drawbacks to using this method. Fragmentation is one possible draw back. When the round strikes a steel plate carrier it can fragment and send the debris into soft-tissue. Also if a polymer tipped round strikes it will not fragment but will send the kinetic energy to the place it strikes. So my suggestion is to have an additional layer of protection between the plate and your body. One option is a layer of Kevlar or polyethylene both in front of your plate and behind this will absorb any kinetic energy or fragments that the round causes.

Physical Considerations for Body Armor

Due to the weight of ballistic plates your joints and ligaments will take a beating, especially if you’re not physically trained. This added weight forces your muscles to work harder.In addition, back injury is likely if your body is not properly trained to carry the additional weight in the correct manner. To correct this include the use of ballistic plates in your combat and survival training.

Addition From User Comment on Kevlar Plates

To me, it makes more sense to use several thinner layers of steel and UHMW polyethylene and a kevlar wrap. Hardening and tempering 2 layers of 1/8in cold roll steel sandwiched like this:

6 layers Kevlar
1/4in UHMW
1/8in steel
1/8in UHMW
1/8in steel
1/4in UHMW
6 layers Kevlar;

should provide a high level of penetration resistance, energy absorption and spalling protection.

The used motor oil provides 2 important parts to the hardening/tempering process. One, it provides additional carbon to the surface of the steel. Two, it slows the cooling process allowing more time for carbon penetration. Yes, this is similar to case hardening but, due to the slower cooling, the carbon goes deeper than case hardening compound. The red-hot quench JDawg speaks of in “forging” is an initial hardening process that aligns the molecules and creates tighter bonds within the metal’s grain. The red-hot quench also equalizes stresses within the metal. The blue heat-quench JDawg speaks of is a stress relieving step, better known as tempering, which adds flexibility to the metal by relieving the surface tension of the work piece.


Is ISIS in America?

Is ISIS in America

If you’re wondering if ISIS is in America, first you’ll need to recognize this… ISIS is just a new name for Islam’s oldest game – killing apostates i.e. Christians, Catholics, the Jewish, and anyone else who doesn’t believe in Muhammad the Prophet. Let’s face it, radical Islam has always been a bunch of little girls with a personality crisis. Today they’re ISIL/ISIS, yesterday they were;  Al Qaeda, Abu Sayyaf, Hezbollah, Hamas, Palestinian Islamic Jihad, Al Fatah, Popular Front for the Liberation of Palestine (PFLP).

ISIS is in America… and they’re counterparts have successfully attacked us over 74 times in the past three decades, with 11 successful attacks in this decade alone. The most noted of these attacks included; the Boston City Bombings, WTC 9/11 Attack, Benghazi (American Soil), and the Fort Hood Massacre. Do you think we’re being too paranoid? I’d hope not, because if you think we are, you’re already lost, brother.

IED use by Terrorists

‘Terrorists would never use an IED in America!’ is a phrase uttered by our daft brethren to the left, and almost always dumbfounded when you tell them the Boston City Bombing was an IED. You literally have to spell it out for them Improvised Explosive Device I.E.D… People don’t understand Islamic Terrorists love to use IEDs – IEDs let them be who they really are… cowards, and nothing more.

According to USA Today, by 2009 over 16,000 IEDs had been detonated or cleared, and 2011 over 4,000 coalition force members had been wounded or killed by IED attacks. Hell, one 90 Day Review of IED attacks distributed to Coalition Forces revealed 708 detonations with 718 casualties – indicating a staggering success rate for IED use.

IED protection for Preppers

Preppers need IED protection! In fact, most Americans should read up on the issue, but hey…half this country has its head in the sand and we can’t expect much. Even if you don’t feel Islamic terrorism warrants cause for concern – you still need to learn IED protection! Sure, Islamic groups have gained recognition for IEDs, but realistically speaking, everyone uses them.

Should the SHTF, and the society implodes on itself, I’m sure IEDs will be used. By design, IEDs are most effective against ‘soft targets’ such as churches, community events, and even an unprotected convoy of prepper vehicles roving the streets of downtown Knoxville.

What is an IED

IEDs are nonstandard explosive devices used to target U.S. Soldiers, civilians, NGOs, and government agencies. IEDs range from crude homemade explosives to extremely intricate remote‑controlled devices FM 3-21.8. Typically an IED is made using artillery rounds packed with high explosives such as white phosphorous or C4 with ammonium nitrate (fertilizer) and shrapnel.

You can spot an IED by looking for exposed wires, cords, or fuzes protruding from an object that shouldn’t have such characteristics, or by noting a difference in smell. Items seeming out of place or a bizarre absence of people are usually a fair indication an IED might be present.

IEDs can be detonated on impact, or remotely using cell phones, pagers, door bell ringers (typically Sega brand) will be used from tall buildings and observation posts that provide a direct line of shit, allowing the attacker to detonate at the right moment.

What is an IED

Why use an IED

Like I said before, it’s a weapon used by cowards to attack soft targets, while an IED itself requires a basic skillset and little cost to make. They can be easily hidden, or disguised alongside the road your Knoxville convoy is traveling down, and can be detonated remotely without the attacked ever exposing his location. As seen in the IED statistics listed above, they are ruthless weapons, and provide an even more damaging effect than what can be seen – psychological warfare.

IED Effects

Once the primary charge is detonated, the gas heats up and expands outward under extreme pressure. This expanding pressure create a blast wave (1,000 x atmospheric pressure) travelling outward anywhere up to 1,600+ ft per second. It then fragments the container and sends shrapnel (nails, pellets, ball bearing, nuts, and bolts) outwards following the blast radius. The heat from the explosion then causes a fire, followed by a small vacuum left by the blast wave pulling the shrapnel back in.

IED Effects

IED effects can differ based upon you (and your convoys) proximity to the blast, if remote detonated it’s safe to assume the attacked waited until you were within the kill zone. Once detonated, the blast wave will flip your shiny little prepper bug out vehicle, while the ball bearings pierce through it and you like an empty soda can leading to; multiple lacerations, internal bleeding, broken bones, loss of limbs, and perforated organs. Even if you made it out with no visible wounds the blast wave alone likely caused your ear drums to rupture which leads to concussion, deafness, blindness, and your brain swelling.

IED Detection

IED detection requires an ever-vigilant trained eye because IEDs can literally be hidden anywhere, and disguised as anything. IEDs can be in burlap bags, animal carcasses, cigarette cartons, potholes, trash, and anything else that most wouldn’t give a second look. A prepper convoy traveling at 35mph would be hard-pressed identifying a disguised IED. I mean, who would notice anything out of place at those speeds?

There is no surefire way of detecting an IED aside from visual confirmation. However, Professor William Fox of the Naval Postgraduate School, along with colleagues from UCSC are currently in the experimental phase using radar signal detection to pick up on IEDs. The technology in its current state is still a couple years out.  Until Fox figures this out, you’ll be stuck using a metal detector to ID IEDs, which will surely expose you, or provide a million false positives.

IED Protection

IED protection has come a long way from the 2001 invasion of Afghanistan. USAF ground troops went from sandbag lined Humvees to the MRAPs (mine resistant ambush protected vehicles). Aside from MRAPs roving the streets of Small Town, USA, they have saved countless US Soldier’s lives with their V shaped hull and layered FK6 armor. Oh you don’t own an MRAP? See our article ‘Retrofitting Civilian Vehicles with Ballistics Armor for Combat and IED Survival’, otherwise you’ll be lining your Dodge Durango with sandbags for weeks.

Another form of IED protection starts with your operational awareness. Whatever operation you taken on always make yourself a hard target. Incorporate IED attacks and roadside ambushes into your survival group’s LFX (live fire exercises). Your well dispersed convoy must be and appear to be vigilant; those who look ready to fight aren’t great targets, making the attacker wait for the next target. Be cautious at choke points i.e. one way roads, blocked roads, sharp turns, and if something causes your convoy to stop – watch your six!


10 must have OTC medications for preppers and 5 you don’t need!

I was at a prepper expo and this question came up… what do you recommend putting in a first aid kit for medications. Now before I go on please look up these drugs on for better information on the safety of these medications and dosing because I don’t feel like plagrizing today and they are more reliable than I am. Also some of the conditions below will be difficult or impossible to diagnose and treat if SHTF. So I am not responsible for any adverse outcomes. As always don’t be something you are not qualified to be… a Doctor.

1. Tagamet (Cimetidine) and/or Omeprazole

Indictations: Acid Reflux and Ulcers.

Omeprazole will reverse the damage and cause of heart burn.

Cimetidine will stop the production of stomach acid. It also is an H2 histamine blocker which is useful in an allergic reaction.

When not to use either: Allergic to the medication. (yes I know that kinda is confusing given the above)

2. Oral Rehydration Salts/Pedialyte

Indications: Hangover and Dehyration secondary to Diarrhea.

This is going to save more lives than any other medication you can buy. Diarrhea is a big killer. Basically what happens is when you have diarrhea there is some bad juju in your stomach. Your body takes fluid from your surrounding tissue and flushes it out. If you have diarrhea you actually need to encourage it. The thing is that this flushing won’t allow for the absorbsion of nutrients from food. So you need to replace fluids and electrolytes (what plants crave).

3. Zinc and Vitamin C

FDA labeled Indications: Wilson’s Disease and Zinc deficiency

Off Label Indications: Acne, ADHD, Burns, Common Cold, Diarrhea, Leprosy, Pnemonia (prophylaxis), Wound Healing.

Zinc promotes your immune system.

4. Honey

Indications: Sore Throat, Cough, Wounds, Hypoglycemia.

Honey has been proven to be a better cough suppressant than Dextromethophan. You can use honey in place of neosporin.

5. Benadryl (topical and oral)

Benadryl is an H1 Antihistamine. It also has the effect of don’t operate heavy machinery when you take it. You can use it for pain management because it is hard to be in pain while you are asleep. It also comes in topical form (which I am hoping you didn’t know about) so it can really help with allergic rashes.

Indictations: allergic reactions, insomnia, motion sickness, parkinsonism, common cold, pruritis of skin

Off Label Uses, Hyperemesis gravidarum (throwing up when pregnant), local anesthesia

6. Acetaminophen and Caffine

Indications: Fever and Pain

Acetaminophen is a Cox-2 inhibitor… That means it blocks pain.  It is also great in reducing fever. Fever is a tricky thing. It is your natural way to kill off an infection but high fevers can cause serious damage. So you need to monitor someones temperature. If someone is 102F or higher then give them some Acetaminophen and plenty of water if they can tolerate it. Now the caffine part is what makes Excedrine the head ache medicine. All excedrine is, is Acetaminophen plus caffine. So coffee has another reason for you to love it.

7. Activated Charcoal

I know this girl who shall remain nameless but she posted what appeared to be a picture of her in black face… what she was doing wasn’t being racially insensitive. She was using Activated Charcoal as a beauty treatment. I will refrain from commenting on the effectiveness of said treatment. What I can comment on is that Activated Charcoal is the first line treatment in pretty much every kind of ingestion induced overdose. It is in water filters and it is in chemical filters for NBC masks and the JSLIST. So the need to stock this is pretty much overwhelming for anyone who is a prepper.

8. Epsom Salts (Magnesium Sulfate) 

Epsom Salts have a lot of prepper uses beyond the medical uses. Let’s not focus on those as they are mostly a replacement for A-Jax and a beauty scrub to exfoliate your skin.

Epsom Salts mixed with water is a POWERFUL laxative. Like don’t make any plans type laxative. One Teaspoon per cup of water and you will empty your bowels.

It is also good topically to soak in a tub with epsom salts as it will releive pain from sore muscles.

Mag Sulfate has also been used for treatment of Cerebral Edema, Barium poisoning, hypomagnesmia, post operative pain, seizures, head aches, eclampsia, and atrial paroxsmal tachycardia. Bad news is that it is an IV solution so you don’t get to have it without a prescription.

9. Baking Soda (Sodium Bicarbonate)

Indications: Metabolic Acidosis 600mg three times a day Orally for your initial dose.

Indigestion: 1-2 (770 mg) tablets Orally every 4 hours in a glass of cool water.

10. Sterile Water or Saline Solution

Wound Irrigation, Eye Irrigation, Ear Irrigation. Sterile Water and Saline take bad stuff and remove it from sensitive areas. If you can find IV bags then you know hypovolemia. Now sure technically you can get Sterile Water IV bags without a prescription but you shouldn’t horde these things because it takes it away from all the people who need them so don’t order a pallet of sterile water. Not that it matters because it is in really short supply anyways.

Drinking plenty of water can also help with all kinds of diseases and disorders. Water naturally balances your PH. It promotes healthy skin. It is pretty much awesome. That is why every medic in the world tells you to drink water.


1. Ibuprofen 

What? Doc Black is saying not to take Motrin??? Should I turn in my medic card? No. Ibuprofen is an NSAID. Or Non-Steroidal Anti Inflamatory Drug. Well what we are finding out is that inflamation is part of the healing process. So if you remove the inflamation you remove the healing.

2. Anti-Diarrheal Medications

again if you stop your body from getting rid of something it doesn’t like you are going to have a bad time.

3. Dextromethorphan (DM) it is just redundant to stock this. Please don’t waste money on it.

4. Antiacids such as tums. 

Antiacids are bad because they absorb stomach acid which feels good and provides immediate relief. Unfortunately your stomach sends signals to your brain and tells it that it doesn’t have enough stomach acid and to make some more. So it does. Then it comes back. So if you are going to use this do so in conjunction with omeprazole or tagament.

5. Antibiotic Ointments

Ladies and Gentlemen and fellow preppers. We are going to soon be facing a post antibiotic world. The infections that used to respond to antibiotics are becoming resistent all over the world. Simply put you are not going to be able to use antibiotics as effectively or at all in the future. So you need to look to some other way to prevent a bacterial infection. There are some interesting new ways coming down the pile line. Until then do not rely on antibiotic ointments to do much for you.
