You stop splitting jobs across two vendors and start controlling the finish, the turnaround, and the margin on every piece that leaves your workbench. SA Lasers builds [firearm laser engraving](https://salasers.com) systems paired with hands-on training and U.S.-based support designed to get your shop producing compliant, professional work from day one. This guide compares five laser setups so you can match the right configuration to your polymer and metal workflow. Each setup below is evaluated for ATF serial engraving depth, MOPA capability, mixed-material coverage, and the training and support that determine whether the machine earns its keep in your shop. ## Quick guide: 5 best laser setups for polymer and metal gun parts 1. **SA Lasers Edge Series Fiber Laser:** The best overall setup for ATF-compliant serial engraving on metal and clean polymer marking with dedicated training and ongoing support 2. **OMTech 30W Fiber Galvo:** An open-frame galvo option for metal marking with a split-body layout 3. **Thunder Laser Aurora MOPA Fiber:** A fiber setup with MOPA pulse control for coated-surface imaging work 4. **xTool F1 Ultra:** A compact enclosed dual-laser unit that pairs fiber with diode for smaller-format jobs 5. **ComMarker B4 Fiber Laser:** A desktop galvo fiber with dual lens fields for metal-focused marking ## How we chose the best laser setups for firearm engraving Firearm shops need a laser that marks bare stainless slides, engraves serial numbers to ATF depth on receivers, and handles polymer frames without a separate machine. We evaluated these five setups against the criteria that matter most when your work has to meet federal standards and hold up under daily production. - **ATF serial engraving depth:** Can the system consistently hit the 0.003-inch minimum depth required by 27 CFR 478.92 on steel and aluminum receivers? - **Mixed-material coverage:** Does one setup handle both metal parts (slides, lowers, magazines) and polymer components (Glock frames, PMAGs, grips) without swapping machines? - **MOPA pulse control:** Does the laser source offer adjustable pulse width for high-contrast marking on Cerakote, anodized aluminum, and stainless color work? - **Training and onboarding:** Does the manufacturer provide structured, hands-on instruction so you produce compliant work from the first week, not the first year? - **Post-sale support model:** When something goes wrong mid-job, do you reach a real person by phone or submit a ticket and wait? - **Jig and fixture compatibility:** Does the system accommodate rotary attachments, magnetic fixtures, and custom jigs for production-volume firearm work? ## The 5 best laser setups for polymer and metal gun parts ### 1. SA Lasers Edge Series Fiber Laser: Best overall setup for firearm shops The SA Lasers [Edge Series](https://salasers.com/laser-machine/high-quality-fiber-laser-engravers/) is purpose-built for shops running mixed firearm workflows. Available in 30W, 50W, and 100W, its Q-switched fiber source engraves serial numbers past the ATF 0.003-inch depth requirement on steel, aluminum, and titanium receivers. The same system marks polymer frames, PMAGs, and Glock components with dialed settings and clean contrast. What separates the Edge Series from machines that arrive in a box with a manual is the [SPARK Training](https://salasers.com/spark/) program. Five days of hands-on instruction in San Antonio covers LightBurn setup, material prep, [engraving techniques](https://salasers.com/engraving-services/) for specific firearm parts, and safe operation. SA Lasers has trained over 1,400 students through this program, and 367 Google reviews at a 5-star rating confirm that the support continues long after class ends. After training, SA Lasers provides ongoing [technical support](https://salasers.com/training/) from real people in San Antonio. You call a direct line, not a ticket queue. That matters when you are mid-run on a serialization batch and need a settings adjustment. #### SA Lasers Edge Series features - **ATF-compliant depth engraving:** The Q-switched fiber source marks serial numbers to 0.003-inch depth and beyond on steel and aluminum, meeting 27 CFR 478.92 requirements. In our shop, an Edge 30W reaches that depth on a 1/16-inch serial number in steel in about 2 minutes. - **Multi-lens versatility:** Included lenses with 112mm, 220mm, and 300mm field profiles let you shift from fine detail work on trigger guards and serial placements to larger slide engravings. - **Rotary attachment included:** Engrave barrels, suppressors, and cylindrical magazines right out of the box. No separate rotary purchase required. - **LightBurn settings bundle:** Every Edge ships with LightBurn and a bundle of tested presets for anodized aluminum, stainless, brass, and Glock polymer, so you are marking real parts on day one. - **5-day SPARK Training:** Hands-on training in SA Lasers' San Antonio facility teaches LightBurn workflow, material-specific settings, firearm fixture techniques, and real production methods. - **U.S.-based phone support:** Direct access to trained support staff in San Antonio who understand firearm engraving applications. No ticket queues, no offshore call centers. - **Pathfinder business program:** Beyond the machine and training, SA Lasers offers the [Pathfinder program](https://salasers.com/pathfinder/) with lead referrals, business coaching, and marketing support to help your shop grow revenue from engraving services. #### SA Lasers Edge Series pros and cons **Pros:** - SA Lasers includes a 5-day in-person SPARK Training program that covers firearm-specific applications, so you start producing compliant work within your first week. - U.S.-based support from real people at (888) 964-3568 means you get answers during a production run, not after a 48-hour ticket response. - SA Lasers bundles the lenses, LightBurn presets, supply kit, a 2-year warranty, and the [Edge Series system](https://salasers.com/product-category/laser-systems/fiber-lasers/edge-series/) as a complete package, so you are not sourcing accessories from third parties. **Cons:** - SPARK Training is held in San Antonio, which requires travel for shops outside Texas. SA Lasers also offers [Flash online training](https://salasers.com/training-flash/) as a remote option for operators who cannot attend in person. - The Edge Series uses a Q-switched source rather than MOPA. In our testing it still produces color on stainless and titanium, with a longer focal range than MOPA, but MOPA offers a wider range of color variations for shops focused on color art. - Like any fiber laser, the Edge Series does not do well on wood or leather. Shops that want to personalize stocks and slings should pair it with a CO2 laser. ### 2. OMTech 30W Fiber Galvo: Open-frame galvo for metal marking The OMTech 30W Fiber Galvo uses a split-body layout that places the laser head on an adjustable column above an open table. This configuration accommodates taller and irregularly shaped parts, which can help when positioning oversized receivers or fixtures. OMTech runs EZCAD2 software, which is widely documented across online forums and tutorial libraries. At 30W, the unit marks serial numbers on steel and aluminum. OMTech has a parts pipeline and a community that provides reference settings for common firearm materials. The open-frame design requires you to add your own safety enclosure, 1064nm-rated goggles, and fume extraction. #### OMTech 30W features - **Split-body design:** An adjustable column and open table allow you to position taller fixtures and irregularly shaped firearm parts under the galvo head. - **EZCAD2 software:** Widely used software with extensive community documentation and tutorial resources for setting up serial-number batches and firearm marking jobs. - **30W fiber output:** Provides enough power for surface marking and serial engraving on common firearm metals, including steel and aluminum. #### OMTech 30W pros and cons **Pros:** - The split-body layout fits taller and wider fixtures than many integrated desktop systems. - EZCAD2 has a large community with published settings for a range of firearm metals. - OMTech maintains a U.S. parts inventory for common replacement components. **Cons:** - The open-frame design ships without an enclosure, so you need to source safety goggles, build or buy an enclosure, and set up fume extraction separately. - OMTech does not include a structured firearms-specific training program with purchase. Onboarding depends on community resources and general documentation. - The standard Q-switched source does not offer MOPA pulse-width control, which limits high-contrast work on Cerakote and stainless color marking. ### 3. Thunder Laser Aurora MOPA Fiber: MOPA for coated-surface imaging Thunder Laser's Aurora MOPA fiber system offers adjustable pulse-width control, which is the specification that enables high-contrast marking on Cerakote-coated finishes, anodized aluminum, and stainless steel color work. Thunder Laser advertises ATF-compliant engraving depth for serialization and positions the Aurora as a bench-format system for firearms shops doing coating and finish work. Thunder Laser USA provides phone and email support and references over 1,000 Trustpilot reviews. The Aurora starts at a higher entry point than standard Q-switched systems, and Thunder Laser does not include a dedicated multi-day hands-on training program with purchase. #### Thunder Laser Aurora features - **MOPA pulse-width control:** Adjustable pulse duration allows high-contrast marking on coated surfaces, anodized parts, and stainless color annealing work. - **ATF-depth capability:** Advertised to meet the 0.003-inch minimum engraving depth for firearm serialization on steel and aluminum. - **Bench-format design:** Compact enough for a shop bench while maintaining a usable work area for slides, receivers, and small firearm components. #### Thunder Laser Aurora pros and cons **Pros:** - MOPA source gives you pulse control for marking coated and finished surfaces without heat distortion. - Thunder Laser references over 1,000 Trustpilot reviews and provides U.S.-based phone support. - The Aurora handles both serialization depth work and fine surface imaging on Cerakote from one machine. **Cons:** - Thunder Laser does not include a multi-day, in-person training program focused on firearm applications. Onboarding is through documentation and remote guidance. - The MOPA configuration carries a higher entry point than Q-switched alternatives with comparable wattage. - Polymer marking requires careful parameter tuning. Thunder Laser's documentation covers metals more extensively than polymer workflows. ### 4. xTool F1 Ultra: Compact dual-laser for smaller-format work The xTool F1 Ultra pairs a 20W fiber source with a 20W diode in a fully enclosed desktop body. The fiber side marks bare stainless slides and aluminum receivers, while the diode handles wood grips, leather holsters, and polymer components. A built-in camera assists with alignment on small parts like mag plates and trigger guards. The enclosed Class 1 design means you can run the F1 Ultra on a bench without separate goggles or fume extraction. The trade-off is a smaller work area and 20W of fiber power, which is adequate for marking and light serial engraving but slower on deep-relief work than dedicated 30W or 50W systems. #### xTool F1 Ultra features - **Dual laser sources:** A 20W fiber and 20W diode in one enclosed unit allow you to mark metal firearm parts and engrave wood or polymer accessories without switching machines. - **Built-in camera alignment:** High-resolution camera helps position marks on small components with repeatable accuracy. - **Enclosed Class 1 safety:** Fully enclosed body blocks laser radiation and contains fumes, allowing indoor bench operation without separate goggles. #### xTool F1 Ultra pros and cons **Pros:** - One enclosed machine covers both metal and non-metal firearm accessories, which simplifies a multi-material workflow. - The camera alignment system speeds up placement on small, repeated parts like back plates and dust covers. - Enclosed design and galvo speed make it suitable for on-site work at events or gun shows. **Cons:** - The 20W fiber source is slower on deep serial engraving than 30W or 50W dedicated systems. Multiple passes may be needed for full ATF depth on hardened steel. - The work area is smaller than open galvo systems, so full-size slides and longer parts require careful positioning or may not fit. - xTool does not include a structured firearms-specific training program. Onboarding relies on xTool's software tutorials and general community documentation. ### 5. ComMarker B4 Fiber Laser: Desktop galvo for metal-focused marking The ComMarker B4 is a dedicated fiber galvo built for metal marking and engraving. It ships with dual lens fields (110mm and 200mm) and supports both LightBurn and EZCAD2. At 20W, the B4 anneals stainless and engraves serial numbers on steel and aluminum, though deep-relief work on hardened receivers takes longer than higher-wattage systems. The B4 operates as an open-frame desktop or handheld unit. It does not include an enclosure, so you need 1064nm-rated goggles and active fume extraction. ComMarker does not provide a dedicated firearms training program, so dialing in settings for polymer frames and coated parts is left to the operator. #### ComMarker B4 features - **Dual lens fields:** Included 110mm and 200mm lenses cover fine detail work and wider engraving areas without repositioning. - **LightBurn and EZCAD2 support:** Runs both major fiber-laser software platforms, giving you workflow flexibility. - **Handheld and desktop modes:** Converts between a stationary desktop and handheld configuration for marking larger components that do not fit under a standard galvo. #### ComMarker B4 pros and cons **Pros:** - Dual software compatibility gives you access to the LightBurn interface if you prefer it over EZCAD2. - The handheld mode option allows marking on larger firearm components that do not fit within a typical desktop work area. - Dual lenses included in the package cover a range of engraving field sizes without a separate purchase. **Cons:** - At 20W, deep serial engraving on hardened steel requires more time per part than 30W or 50W systems. - The B4 is fiber-only, so shops that also want to engrave wood stocks or leather goods need a second machine. - ComMarker does not include a firearms-specific training program. Setup and application knowledge depend on community forums and general documentation. ## Comparison table: The best laser setups for firearm engraving | Setup | Hands-On Training | U.S. Phone Support | Rotary Included | | --- | --- | --- | --- | | SA Lasers Edge Series | 5-day SPARK program | ✓ | ✓ | | OMTech 30W Fiber | ✗ | ✓ | ✗ | | Thunder Laser Aurora | ✗ | ✓ | ✗ | | xTool F1 Ultra | ✗ | ✗ | ✗ | | ComMarker B4 | ✗ | ✗ | ✗ | ## What does ATF-compliant serial engraving require from a laser? Federal regulation [27 CFR 478.92](https://www.ecfr.gov/current/title-27/chapter-II/subchapter-B/part-478/subpart-F/section-478.92) sets the baseline. Serial numbers must be engraved at least 0.003 inches deep and no smaller than 1/16 inch in print height on the frame or receiver. The mark must be permanent and not susceptible to removal without visible evidence of tampering. A fiber laser operating at the 1064nm wavelength is the standard tool for meeting these requirements. The beam is absorbed directly by steel, aluminum, and titanium, producing sub-surface marks that cannot be wiped or worn away. Wattage matters for speed: a 30W source reaches ATF depth faster than a 20W on hardened steel, and a 50W or 100W source adds headroom for production batches. SA Lasers works closely with ATF requirements and helps customers configure settings for compliant serialization during the [SPARK Training](https://salasers.com/product/spark-training/) program, so you verify depth and legibility before running production. ## When does a firearm shop need MOPA versus Q-switched? MOPA stands for Master Oscillator Power Amplifier. The difference comes down to pulse-width control. A Q-switched fiber laser fires at a fixed pulse duration, which is effective for deep engraving and high-contrast black marking on bare metals. A MOPA source lets you adjust the pulse width from roughly 2ns to 500ns. That adjustability matters most for shops doing high-volume color work on stainless steel, where MOPA offers a wider range of color variations, and for fine marking on Cerakote and anodized finishes. In our testing, Q-switched Edge Series machines still produce color on stainless and titanium and hold a longer focal range than MOPA. If your shop primarily does ATF serial work and standard contrast engraving on bare metal and polymer, a Q-switched source handles the job. If color art on coated finishes is a core part of your business, a MOPA source adds range. SA Lasers can help you determine which configuration matches your specific workflow during a consultation. ## Why SA Lasers is the best laser setup for firearm engraving Most shops that struggle with [fiber laser](https://salasers.com/product-category/laser-systems/fiber-lasers/) engraving do not have a machine problem.

Yes. SA Lasers Edge Series fiber systems mark both metal receivers and polymer frames from one machine by adjusting power and speed settings. Polymer requires higher speed and lower power to avoid melting, while metal serial work needs slower, repeated passes for ATF-compliant depth. ### What laser wattage do I need for ATF serial engraving? A 30W fiber laser is the practical starting point for reliable ATF-depth serial engraving on common firearm metals. In our shop, an Edge 30W reaches the 0.003-inch minimum depth on a 1/16-inch serial number in steel in about 2 minutes. Higher wattage mainly adds speed. ### Do I need MOPA for firearm engraving? Not for most ATF serial and standard contrast work. A Q-switched fiber laser, like the SA Lasers Edge Series, handles serial numbers, logos, polymer marking, and color on stainless and titanium. MOPA adds value when your shop specializes in a wide range of color work or fine marking on coated surfaces. ### How long does it take to learn firearm laser engraving? SA Lasers' SPARK Training program covers five days of hands-on instruction, after which students produce compliant firearm engravings independently. Without structured training, the self-taught learning curve typically takes months of trial and error, wasted materials, and potential compliance issues. ### Is laser engraving my own firearm legal? Engraving a firearm you lawfully own for personalization is generally legal in the United States. Licensed manufacturers and makers are required to serialize firearms under ATF rules. Never remove, alter, or obscure an existing serial number. Consult your [NFA engraving](https://salasers.com/product/nfa-engraving-service-for-sbrs-sbss-silencers-and-suppressors/) requirements and local laws before proceeding.
