How To Clean AR15 Barrel

By /

While stainless steel barrels might resist corrosion better than other types, they still need regular cleaning to remove fouling and maintain accuracy. This is your guide on how to clean AR15 barrel. While the barrel is crucial, other parts of the AR-15, like the bolt carrier group, also need regular maintenance to ensure the firearm functions correctly.

Why Clean Your Barrel?

  • Accuracy: A dirty barrel can mess up your shots.
  • Reliability: A clean gun works better and jams less.
  • Long Life: Taking care of your gun means it'll last longer.

Basic Cleaning: What You Need

Imagine you're getting ready for a fun day at the range. Before you start, you'll need some tools to keep your AR-15 in top shape:

  • Cleaning Rod: Think of it like a toothbrush for your gun. It should be longer than your barrel and won't scratch it.
  • Patches: These are like the toothpaste. Don't use paper towels; they'll leave stuff behind.
  • CLP: It's a 3-in-1 magic liquid: it cleans, lubes, and protects.
  • Barrel Brush: This is like a scrub brush for tough spots. Make sure it fits your gun's size.
  • Chamber Brush: This is a special brush just for the chamber of your AR-15.
  • Patch Loop or Jag: This helps you push patches through the barrel.

Or, if you want an all-in-one solution, grab an Otis AR-15 cleaning kit + Breakthrough CLP kit. It's like a toolbox for gun cleaning.

Basic Cleaning Steps

  1. Spray gun cleaning oil on the BCG, charging handle, and inside of the upper.
  2. Wipe off the excess oil and grime.
  3. Reapply a light coating of oil/lube before putting everything back together.

Pro Tip: If you've been firing a lot, especially with dirtier ammo like steel case, you'll want to give your bolt some extra attention to keep things running smoothly.

Over-lubrication can attract dirt and debris, which can cause malfunctions. It's crucial to apply the right amount of lubricant, focusing on the areas that need it most.

Step-by-Step Cleaning

  1. Take Apart Your AR-15: Remove the bolt carrier group and charging handle. If you have a vice or gun rest, use it to hold your gun.
  2. Use the Bore Guide: If you have one, put it in now.
  3. Clean the Barrel:
    • Wet a patch with CLP and push it through the barrel.
    • Always move from the chamber to the muzzle, like how a bullet travels.
    • Use a fresh patch to pick up the dirt.
    • Use the bronze barrel brush with some CLP to scrub inside.
    • Check the barrel. If it's still dirty, repeat until it's clean.
    • For a quick clean, you can use a Boresnake or Ripcord.

Deep Cleaning for the Pros

If you want your barrel to be super clean:

  1. Use Solvent: After using CLP, use a nylon brush with bore cleaner.
  2. Let It Sit: Some solvents need time to work. Check the instructions.
  3. Clean with Patches: Push fresh patches through until they come out clean.
  4. Final Touch: If you're storing your gun for a while, add some oil or CLP to protect it. Remember to wipe it out before shooting again.

Pushing and pulling brushes repeatedly can wear out the brush and the barrel's rifling. It's best to push the brush through and then remove it to re-enter from the chamber side.

Don't Forget the Chamber!

The chamber is super important. If it's dirty, your gun might not work right.

  1. Use the Chamber Brush: Wet it with CLP and scrub inside.
  2. Clean Behind the Lugs: This spot is easy to miss, but super important.
  3. Wipe It Down: Use patches to pick up the dirt.

Pro Tips for Easy Cleaning

Want to make cleaning easier next time? Try these tricks:

  • Clean at the Range: Bring a small kit with you. After shooting, clean your gun while it's still fresh.
  • Use a Boresnake: It's a quick way to clean on the go.
  • Regular Cleaning: Clean your AR-15 every 500 rounds. If you're a sharpshooter, you might need to clean it more often.
