Step 2: Unload and Disassemble the CZ Scorpion Evo 3

With a firm understanding of the necessity for proper maintenance, it’s time to dive into the meat of our guide – unloading and disassembling your CZ Scorpion Evo 3. Safety must always come first. So, before we delve into the disassembly process, let’s make sure your Scorpion is secure and unloaded.

To unload your firearm, you’ll want to follow these simple steps:

  1. Point the firearm in a safe direction.
  2. Engage the safety.
  3. Remove the magazine.
  4. Pull back the charging handle and inspect the chamber to make sure it’s empty.

Moving on to the disassembly.

CZ Scorpion Evo 3’s are known for their user-friendly design. That extends to the disassembly process which, aside from requiring a careful hand, is fairly simple once you get the hang of it.

Here’s how it’s done:

  1. Push out the main pin from the lower receiver. This will disconnect the trigger group.
  2. Pull the charging handle to the rear and remove the bolt carrier and bolt.
  3. Finally, drive out the front pin to remove the handguard.

Note that, while not removing it, you can further disassemble your Scorpion by unscrewing the barrel nut and removing the barrel for complete cleaning. However, this isn’t necessary as often.

By following these outlined steps, you’ll have your CZ Scorpion Evo 3 broken down and ready for a thorough cleaning. Despite the seemingly complex task of disassembling a firearm, practice makes perfect.

The next part of our guide will delve into the cleaning process. It covers what elements to focus on and some best practices for firearm cleaning. You don’t want to miss it.

Step 3: Clean the Barrel and Chamber

Now that your CZ Scorpion Evo 3 is unloaded and disassembled, it’s time for the main task. Cleaning the barrel and the chamber – arguably the heart and veins of your firearm. This step ensures better accuracy, smoother action, and longer component life.

Before you start, always remember that safety is paramount. When you’re handling cleaning chemicals and precision equipment, you want to remain cautious. Consider using gloves and eye protection if you’re sensitive to cleaning solvents.

Pick up your bore brush or bore snake, apply a small amount of cleaning solvent on it and gently clean the inside of the barrel. Remember to lead with the bristle end if you’re using a bore brush. Start from the rear (chamber end) and work your way down the barrel.

Note: Do not pull a bore brush backward through the barrel. This could damage the precision rifling. Always push it all the way through and then take it out and restart from the chamber end.

CZ Scorpion Evo 3 has a user-friendly barrel design. I’ve always found it easier to clean compared to many other firearm models.

After brushing, you’ll notice that the solvents have loosened up the dirt and grime inside the barrel. Now use a clean patch on a jag, push it through the barrel to remove the junk. Repeat this process until the patches come out clean.

Onto the chamber. Use a chamber brush dipped in solvent. Firmly scrub the walls of the chamber, focusing on any areas with stubborn buildup.

As with the barrel, follow this with a clean, dry patch or a mop to remove any lingering solvent, along with the debris it’s dislodged. Repetition is key – continue the process until the patches come out clean.

That’s it – the barrel and chamber of your CZ Scorpion Evo 3 are now clean. This maintenance task will definitely enhance the longevity and performance of your firearm. In the next segment, we’re going to tackle how to clean the bolt group – an equally crucial part of the firearm. I’ll provide a step by step guide so you’ll be fully prepared for the task ahead.

Step 4: Clean the Bolt Assembly

Bolt assembly is another critical component to address when maintaining your CZ Scorpion Evo 3. Like all other parts, its effective operation is key to the firearm’s overall performance. Let me walk you through the process.

Start with a well-ventilated area and prepare your cleaning supplies. You’ll need your cleaning solvent, lubricant, lint-free cloth, and detail brush. Remember, safety is paramount when handling and cleaning your firearm.

Place the bolt assembly on a clean, flat surface. Dip your detail brush into the cleaning solvent, then use it to scrub the bolt and the firing pin. Pay attention to the bolt face and the extractor – residue in these areas can compromise the accuracy and reliable function of your scorpion. Ensure you’re thorough but gentle, to avoid damaging any components.

Once you’ve removed surface grime, take your lint-free cloth and slightly dampen it with cleaning solvent. Use this to wipe down the bolt assembly, focusing on the areas where the carbon buildup is often substantial, such as the bolt face and extractor. Wipe until no further residue comes off on your cloth.

Apply a drop or two of lubricant to the bolt and firing pin. It’s vital to ensure that these parts move smoothly during their action cycle. Remember, a little lubricant goes a long way—you don’t want to overdo it and have excess oil collecting dust and dirt.

Step 5: Wipe Down the Receiver and Other Exterior Parts

Now that we’ve thoroughly cleaned the bolt assembly, let’s move onto the receiver and other exterior parts of the CZ Scorpion Evo 3. Keeping these components clean is equally crucial for the longevity and performance of your firearm.

First off you’ll want to grab a clean, lint-free cloth. Be sure to dampen the cloth with a bit of cleaning solvent. It’s not necessary to saturate it – a light dampening will do. With your cloth ready, it’s time to get to work.

Hold your firearm carefully, ensuring that the safety is engaged. Start by gently wiping down the receiver. This part of your weapon can accumulate dirt and grime, particularly after extensive shooting sessions. It’s imperative to keep it clean as much as possible. Pay particular attention to crevices and tiny corners where residue is prone to build up.

Once you’re done with the receiver, focus on the exterior parts. From the guard rails to the muzzle, give every component a nice wipe. While doing so, always remember to move your cloth in one direction, not back and forth. This technique helps pull dirt away from the firearm, rather than rubbing it in further.

You might also want to give an extra wipe to the barrel’s exterior. It’s exposed to lots of heat during firing and therefore may have more stubborn residue. Use a new area of your cloth for this.

After wiping, follow up with a dry, soft brush. This will help remove any lingering solvent that may be hiding in the corners. Just like with cloth, always brush in one direction.

And there you have it – a clean receiver and shining exterior parts, all set to offer uncompromised, smooth performance. So, let’s roll up our sleeves and get on to the next step.

Step 6: Lubricate the Moving Parts

Now that we’ve wiped down the receiver and exterior parts, it’s crucial not to forget about lubricating the moving parts of your CZ Scorpion Evo 3. Proper lubrication is key to ensuring smooth operation and reducing unnecessary wear and tear on your firearm. With adequate lubrication, you’ll find your firearm performs better and lasts longer.

Choose a high-quality gun lubricant—avoid common household oils and lubes, as they’re not formulated for the unique requirements of firearms. Once you’ve selected your lubricant, apply it sparingly. Contrary to what you might think, more lubricant doesn’t necessarily mean better lubrication. In fact, too much lube can attract dirt and grit, which can hamper your firearm’s performance.

Lubricate the bolt carrier group first. By doing so, you’re reducing friction, hence mitigating wear. Apply a drop of lube on the rails and rollers of the bolt group, then ensure it’s evenly spread by cycling the bolt a few times.

Next, lubricate the trigger assembly. It contains multiple moving parts, so pay special attention to this area. A little bit of lube on the trigger mechanism goes a long way in keeping your firearm in top shape.

Finally, attend to the recoil spring and guide rod. They play a vital role in the firearm’s recoil operation, so don’t neglect them. Apply your lube sparingly on the spring and guide rod, then spread it evenly.

That’s it for lubricating the moving parts. But before you move on, remember: a well-lubricated firearm is a well-functioning firearm. It’s as simple as that. Now, let’s move on to reassembling the Scorpion Evo 3—which I’ll be covering next.


So there you have it – the essential steps to keep your CZ Scorpion Evo 3 in top shape. Remember, a well-lubricated firearm isn’t just about performance; it’s also about longevity. By applying a high-quality gun lubricant sparingly, you’ll ensure smooth operation and reduce wear and tear. It’s a simple process, but one that can make a world of difference in your firearm’s functionality. Whether it’s the bolt carrier group, trigger assembly, or recoil spring and guide rod, each component benefits from proper lubrication. So, don’t skimp on this crucial maintenance step. Your CZ Scorpion Evo 3 will thank you with reliable performance for years to come.
