What is DLC Gun Coating Service?

DLC, or Diamond-Like Carbon coating, is a high-performance finish applied to firearm components. It uses advanced technology to provide a durable, attractive, and smooth surface. This coating service enhances a gun’s longevity, resistance to wear, and overall aesthetics. If you want your firearm to have superior protection and a sleek look, DLC coating is a top choice among gun owners and professionals.

How Does the DLC Gun Coating Process Work?

Understanding the process can help you appreciate its value. Here’s a step-by-step overview of how a typical DLC coating service is performed on firearms:

  1. Preparation and Cleaning
  2. Parts are carefully disassembled.
  3. Each component is cleaned to remove oil, dirt, and old coatings.
  4. Surface imperfections may be polished out for optimal coating.

  5. Pre-Treatment

  6. The parts often undergo a special etching or surface treatment.
  7. This promotes maximum bond between the metal and the DLC layer.

  8. Coating Application

  9. The DLC coating is usually applied through a Physical Vapor Deposition (PVD) process.
  10. In a vacuum chamber, carbon atoms are deposited onto the firearm components, forming a thin, diamond-hard layer.

  11. Curing and Inspection

  12. The coated parts are cured (if necessary) and cooled.
  13. Technicians inspect surfaces for quality control, ensuring an even and flawless finish.

  14. Reassembly and Function Check

  15. Once coating passes inspection, your firearm is reassembled.
  16. Function checks are performed to verify smooth operation.

  17. Shipping or Pickup

  18. The finished firearm can be shipped to your address or picked up at the service location.

Benefits of DLC Gun Coating

Many gun owners invest in DLC coating for a good reason. Here’s what makes it so valuable:

  • Extreme Hardness: DLC’s surface is often much harder than steel, providing robust protection.
  • Superior Wear Resistance: Reduces friction and metal-to-metal wear, significantly extending firearm life.
  • Corrosion Protection: Shields parts from rust, humidity, and corrosive environments.
  • Low Maintenance: Easier cleanup—DLC surfaces typically shed fouling and grime more readily.
  • Sleek Appearance: Results in a uniform, deep black or graphite finish that’s both modern and attractive.
  • Smooth Operation: Its slickness can enhance trigger pulls and slide action on pistols or rifles.

Common Firearm Parts for DLC Coating

You can DLC-coat a variety of gun parts, including:

  • Slides and frames (especially on pistols)
  • Barrels
  • Bolt carriers and bolts (for AR-style rifles)
  • Hammers and triggers
  • Extractors and other internal components

DLC is commonly sought after for high-wear areas and critical moving parts.

Possible Challenges and Considerations

DLC coating offers many perks, but there are things to keep in mind:

  • Cost: It’s a premium service, typically more expensive than standard finishes. Prices depend on the part, complexity, and provider.
  • Turnaround Time: Since the process involves shipping, cleaning, coating, and inspection, expect a lead time of several weeks.
  • Shipping and Legal Compliance: Firearms sent for coating must comply with all local and federal laws. Properly package your firearm parts and follow shipping guidelines.
  • Color Options: DLC is generally available in shades of black and grey, so if you want other colors, alternative coatings may be necessary.
  • Compatibility: Some gunsmiths or coating providers may not offer DLC for all types of metals or firearm models.

Practical Tips for Using DLC Gun Coating Services

Choosing the right service and caring for your new DLC coating is important for long-term satisfaction. Here are essential tips:

Before Sending Your Firearm

  • Contact Service Providers: Ask about their experience with your firearm type. Some, like DNA Firearm Systems and Vulcan Machine Werks, specialize in particular models or parts.
  • Check for Disassembly Requirements: Some shops require that your firearm is shipped fully disassembled; others may offer this service for a fee.
  • Confirm Shipping Details: Insure your package, use secure carriers, and follow legal shipping procedures for firearms or parts.

Selecting a Provider

  • Look for Experience: Choose a provider known for DLC expertise and positive customer reviews.
  • Ask about Turnaround Time: Understand how long the process will take.
  • Request a Quote: Get clear pricing for DLC application, as costs can vary by complexity and coverage.

After Receiving Your DLC-Coated Firearm

  • Inspect the Work: Check for a smooth, even coating with no runs, bubbles, or missed spots.
  • Function Test: Dry-fire and manipulate all controls to be sure the coating has not negatively affected the mechanical function.
  • Routine Cleaning: DLC coatings make cleaning easier, but still follow proper maintenance routines.
  • Avoid Abrasives: Use soft cloths and non-abrasive cleaners to preserve the finish.

Cost Tips

  • DLC coating can range from $150 to $400 or more, depending on the part.
  • Shipping both ways can add $40–$60, especially for insured or express packages—combine parts to save money.
  • Some shops offer package deals for multiple parts or complete firearms.
  • If you live near a reputable shop, in-person drop-off and pick-up can save shipping costs and reduce turnaround.

Best Practices for Maximum Results

To get the most out of your DLC-coated firearm:

  • Communicate Clearly: Tell your service provider exactly which parts you want coated and any critical tolerances.
  • Maintain Proper Lubrication: Although DLC reduces friction, a little lubrication still helps maximize performance.
  • Routine Inspection: Even with a hard surface, regularly examine your gun for any signs of unusual wear or issues.
  • Document Serial Numbers: Write down your firearm’s details before shipping, for your peace of mind.

In Summary

DLC gun coating is an advanced, highly durable finish that offers exceptional benefits for both firearm protection and aesthetics. While it may require an upfront investment and lead time, the long-term payoff in performance, ease of cleaning, and sheer toughness makes it a favorite among discerning gun owners. By selecting a reputable DLC coating service, you can give your firearm a professional look and an armor-tough upgrade that lasts.


Frequently Asked Questions (FAQs)

What is DLC coating and why is it so popular for firearms?

DLC (Diamond-Like Carbon) coating is an ultra-hard, slick surface applied to metal parts, especially firearms. It’s popular because it provides unmatched wear, corrosion resistance, and a modern black appearance, making guns more durable and easier to maintain.

Can I have my entire firearm DLC coated, or just specific parts?

While you can DLC-coat many parts, most owners focus on high-wear components such as slides, barrels, bolt carriers, and triggers. Some internal polymer or non-metal parts cannot be DLC coated. It’s best to consult your chosen provider for compatibility with your firearm.

How long does the DLC coating process usually take?

Turnaround time varies by shop and volume, but typically it ranges from 2 to 6 weeks. This includes disassembly, cleaning, coating, inspection, and any required shipping. Always ask your service provider for a time estimate.

Will DLC coating change the way my gun functions?

A professionally applied DLC coating should not change the mechanical function or dimensions if the process is performed correctly. In fact, the smooth surface may improve cycling and reduce friction. Always inspect and test your firearm after receiving it back.

How should I care for my DLC-coated firearm?

DLC finishes are very low-maintenance. Regular cleaning with mild cleaners and soft cloths is enough. Do not use abrasives or harsh chemicals. Although DLC is extremely hardy, routine inspection and proper lubrication help maintain the best performance.


With an understanding of how DLC gun coating services work, you can make an informed decision about whether this modern finish is right for your firearms. Enjoy the lasting protection, sleek appearance, and trustworthy performance that DLC provides!
