Built for Firearms Manufacturers Who Can’t Afford Guesswork

Firearms components aren’t like typical machined parts. The stakes are higher. The tolerances are tighter. The risks are greater.

That’s why firearms OEMs choose Nel PreTech:

Make confident decisions

Youreceive accurate data, comprehensive dimensional reports, and engineeringreview that helps you validate fit, function, and safety.

Measure complex, internal, and hidden features

Our CT scanning systems capture areas CMM probes can’t reach, revealing defects, voids, porosity, or assembly issues before they become failures.

Trust an accredited, licensed, and defense-ready facility

  • A2LA ISO/IEC 17025 accreditation
  • FFL 07 manufacturing license (safe handling of regulated components & suppressors)
  • ITAR-compliant processes and secure chain-of-custody

What This Means for Firearms OEMs & Component Makers

Fewer rejects. Fewer failures. More reliable production.

CT and CMM inspection eliminate uncertainty by capturing true part geometry, revealing issues long before they impact performance or compliance.

Faster prototyping and product iteration

Launch new firearms, accessories, or replacement parts with rapid inspection that gives engineering teams immediate feedback.

Better control over suppliers and contract manufacturers

With independent dimensional validation, you always know whether incoming parts meet your specifications.

Reduce waste, rework, and costly scrap

High-accuracy data helps you adjust machining, casting, or molding processes early—saving significant time and material costs.

Strengthen compliance for government, defense, or regulated contracts

With FFL 07, ISO 17025, and ITAR compliance, your inspection partner is fully aligned with industry and legal requirements.

Firearm Components We Commonly Inspect

  • Barrels (rifled, smoothbore, pistol, carbine)
  • Bolt carriers, bolts & slides
  • Frames, lowers, uppers
  • Fire control groups
  • Triggers, sears, hammers
  • Suppressors & serialized components
  • Magazines & feed systems
  • MIM, cast, or forged components
  • Multi-component assemblies

If it must be dimensionally perfect, structurally sound, or validated inside and out, we can inspect it.

Barrels & Related Components:

  • Rifled barrels (pistol, carbine, rifle, precision, match-grade)
  • Smoothbore barrels (shotgun, less-lethal systems)
  • Chamber sections & throats
  • Barrel extensions
  • Gas ports & gas blocks (alignment checks)
  • Barrel nuts & retention systems
  • Muzzle devices (flash hiders, brakes, compensators)
  • Threaded sections & suppressor interface geometry
  • Bore erosion/wear studies (CT ideal)

End-User Benefits at a Glance

FAQ — Firearms Component Inspection

Do you accept regulated or serialized firearm components?

Yes. Nel PreTech is an FFL 07 licensed manufacturer, which allows us to legally receive, inspect, store, and ship regulated components — including serialized receivers and suppressors.

Are you ITAR compliant?

Yes. We maintain secure data handling, restricted access, and controlled processes to meet ITAR requirements.

How do I know whether I need CT scanning or CMM inspection?
  • Use CMM for surface-level, dimensional features with clear line of sight.   • Use CT when you need to see internal geometry, hidden features, or potential defects.  Our engineers will recommend the best method for your specific component.
  • Use CT when you need to see internal geometry, hidden features, or potential defects. Our engineers will recommend the best method for your specific component.
Can you detect internal barrel defects?

Yes. CT scanning can reveal tool marks, voids, cracks, erosion, wall-thickness variations, and deformation inside barrels.

How fast is turnaround?

Most projects are completed in days to one week, depending on part complexity and reporting requirements.

What file formats do you provide?

PDF, Excel, STL, IGES, point clouds, color maps, and CAD deviation reports.

Can you inspect complex assemblies?

Yes. CT scanning is excellent for analyzing multi-part assemblies without disassembly.
