Precision Cuts Through Everything.
SWORDFISH, L.L.C. designs, builds, and services premium firearms, custom rifle platforms, and tactical equipment for professionals, collectors, and responsible owners who refuse to compromise on craftsmanship, safety, or accuracy.
Built Like a Blade, Engineered Like a Rifle
A swordfish is nature's precision instrument — hydrodynamic, singularly focused, and built for decisive speed. We apply that same philosophy to every firearm, build, and service that leaves our Denver facility: no wasted motion, no shortcuts, and absolutely no compromise between form and function.
Precision Engineering
Every build is machined and fitted to tolerances measured in thousandths of an inch, verified on calibrated equipment before it ever reaches your hands.
Rigorous Safety Standards
Multi-point safety inspections, function testing, and documented quality checks accompany every firearm and component we handle, sell, or service.
Master Craftsmanship
Our gunsmiths bring decades of combined experience in custom builds, precision gunsmithing, and restoration of classic and modern platforms alike.
Full Legal Compliance
Every transaction follows federal, Colorado state, and local regulations, including required background checks, recordkeeping, and licensed-dealer transfers.

From ground-up custom builds to precision optics and ongoing maintenance, our capabilities are organized around one goal: giving you a firearm platform you can trust without hesitation.

Nothing Leaves Our Shop Without Being Verified
Precision is only real if it can be measured. That's why every build, repair, and installation that passes through our Denver facility follows a documented quality-assurance process from the moment a component arrives to the moment a finished product leaves our hands.
Sourced Responsibly
We work only with reputable manufacturers and licensed distributors, verifying authenticity and specification on every component before it enters a build.
Calibrated Tooling
Our gunsmithing bay uses regularly calibrated measuring and machining equipment, so tolerances stay consistent from the first build to the thousandth.
Documented Testing
Function tests, safety checks, and fit verification are logged for every project, giving you a clear record of exactly what was done and confirmed.
One Point of Contact. Zero Wasted Motion.
The swordfish is among the fastest creatures in the ocean — not because it is the largest or strongest, but because every part of its body is aligned toward one purpose. That singular focus is the standard we hold ourselves to: whether we're fitting a trigger group, zeroing an optic, or walking a first-time buyer through a compliant purchase, everything we do is aligned around precision and trust.
We call it the Swordfish Standard — a commitment to cutting away everything unnecessary, so what remains is faster, cleaner, and built to perform when it matters.
It shows up in small ways too: a callback returned the same day, a straightforward explanation of a legal requirement instead of a runaround, and a willingness to say "that's not the right build for you" when a different configuration would genuinely serve you better. Precision, to us, is as much about honesty as it is about tolerances.
Trusted By Professionals & Collectors
"The attention to detail on my custom build was on another level. Every screw, every tolerance, explained before I ever paid a deposit."
"As a first-time buyer I appreciated how thoroughly the team walked me through the legal process. Zero pressure, all patience."
"Sent in a family heirloom rifle for restoration. It came back looking & functioning better than when it was new."
About Swordfish
A Denver-built company grounded in precision engineering, legal compliance, and a genuine respect for the responsibility that comes with firearms ownership.
Named For A Predator Built On Focus
SWORDFISH, L.L.C. was founded in Denver, Colorado by a small group of gunsmiths, engineers, and range instructors who shared a single frustration: too many firearms businesses treated precision as an upsell rather than a baseline. We set out to build a company where accuracy, safety, and legal compliance weren't separate departments — they were the entire foundation.
The name is deliberate. A swordfish is one of the ocean's most efficient predators, not because of brute size, but because its entire body — from its elongated bill to its rigid, hydrodynamic frame — is optimized around a single trajectory. There is no wasted motion. We wanted our company to feel the same way: lean, purposeful, and precise in everything from how we machine a barrel to how we walk a customer through a background check.
Today, from our facility on East Jefferson Drive, we serve clients across Colorado and, through compliant shipping to licensed dealers nationwide, customers across the United States — ranging from first-time owners to competitive shooters and long-time collectors.
What hasn't changed since our first small workshop is the belief that a firearms business earns trust one careful, well-documented interaction at a time. We would rather take an extra ten minutes explaining a legal requirement or a fitting decision than rush a customer toward a sale they aren't fully confident in. That patience is, in its own way, part of the craftsmanship we're known for.
What Guides Every Decision We Make
Our mission is simple: deliver precision-built firearms and equipment through a process that is transparent, compliant, and respectful of the seriousness of what we sell. These five values shape every interaction, whether it's a first phone call or a decade-long service relationship.
Safety First, Always
Every recommendation we make prioritizes safe handling, safe storage, and safe operation above all else.
Uncompromising Compliance
We follow ATF regulations, Colorado state law, and local ordinances to the letter, with documentation to match.
Precision Over Volume
We would rather deliver one perfectly fitted build than ten rushed ones.
Customer-Centered Guidance
No pressure, no upselling — just honest guidance based on your intended use and experience level.
Our Journey So Far
Swordfish Is Founded
Opened our first small workshop in Denver focused exclusively on custom gunsmithing and repairs.
Facility Expansion
Relocated to our current East Jefferson Drive facility, adding a dedicated optics fitting bay.
Certified Technician Program
Formalized ongoing training and certification requirements for every gunsmith on staff.
Community Safety Initiative
Launched free seasonal safe-storage and handling workshops for local first-time owners.
Nationwide Reach
Serving clients across the country through compliant dealer-to-dealer transfers and remote consultations.
Two Words We Never Separate
Craftsmanship without compliance is a liability. Compliance without craftsmanship is just paperwork. We treat them as a single discipline.
Licensed Process
All firearms transactions are conducted in accordance with federal licensing requirements, including mandatory background checks and transaction recordkeeping.
Certified Gunsmiths
Our technicians maintain ongoing manufacturer and armorer-level certifications across the platforms we service most frequently.
State-Aware Guidance
Because firearms laws vary widely, we verify state and local requirements before every shipment or transfer — no exceptions.
Responsible Ownership Is Part Of The Product
We believe a firearm sold without proper education is an incomplete transaction. That's why every purchase at Swordfish includes a conversation about safe storage, safe handling, and local legal obligations — not as an afterthought, but as a core part of the service.
Our team regularly partners with local ranges to host safe-handling clinics, and we maintain relationships with certified instructors we're glad to refer clients to for hands-on training, regardless of experience level.
We also encourage every client, new or experienced, to think seriously about secure storage solutions appropriate for their household. A great firearm paired with poor storage practices is still a serious risk, and our team is always happy to talk through options that fit your living situation.
Products & Services
Every category below is backed by the same process: careful consultation, precise execution, thorough testing, and full compliance from first call to final delivery.
A Complete, Compliant Catalog
From ground-up custom builds to ongoing maintenance, our capabilities are organized to cover the full lifecycle of firearm ownership — always through licensed, documented channels. Whether you're starting your very first build or refining your fifteenth, the same specialists and the same documented process apply, regardless of project size or budget. Browse the categories below, then reach out and we'll help you narrow things down.

Bespoke rifle and pistol platforms engineered around your intended use, whether that's competition, hunting, duty, or collection. We source components, machine to spec, and hand-fit every build before final function testing.
Precision Optics & Sights
Selection, mounting, and professional zeroing of scopes, red dot sights, and iron sight systems, matched to your platform, distance requirements, and lighting conditions.
Tactical Gear & Accessories

Gunsmithing & Maintenance
Deep cleaning, refinishing, trigger and action work, and full diagnostic servicing performed by certified technicians using manufacturer-approved procedures.

Training & Range Referrals
Guidance toward certified instructors and range partners for safe-handling courses, marksmanship fundamentals, and platform-specific familiarization.
Where Every Component Comes From
Quality starts long before a build reaches our workbench. We source barrels, actions, optics, and furniture exclusively from established manufacturers and licensed distributors, verifying part authenticity, batch specifications, and material certifications before anything is approved for use in a client build.
For finishing work — coatings, cerakote, and refinishing — we use industrial-grade processes designed to hold up under repeated field use, not just look good on a showroom shelf. If a component doesn't meet our internal standard, it doesn't go out the door, regardless of how far along a project already is.
How A Custom Build Comes To Life
Five deliberate stages, each documented and confirmed with you before we move to the next. You'll always know what phase your build is in and what happens after it.
Consultation
We discuss intended use, budget, and legal requirements in your state.
Design & Engineering
Component selection and technical specification tailored to your goals.
Precision Assembly
Hand-fitted assembly performed by a certified gunsmith on calibrated tooling.
Testing & QC
Function and safety testing against documented quality-control checklists.
Delivery & Walkthrough
Compliant transfer plus a full walkthrough of operation, care, and storage.
Every Purchase Follows The Same Rulebook
Regardless of product category, every transaction that requires it is processed through a completed background check via the required federal system, accurate identity verification, and full compliance with Colorado state law and any additional requirements in the buyer's home state.
Age, residency, and documentation requirements apply to every firearm sale and transfer. Our staff will always explain these requirements clearly before any transaction begins, and we reserve the right to decline any sale that cannot be completed in full compliance with applicable law.
The Relationship Doesn't End At Pickup
A build is only as good as the support behind it, so we stay involved well after a project or purchase is complete. Firearms are mechanical tools that see real wear over years of use, and we'd rather see you back in our shop for a tune-up than see a preventable issue go unaddressed.
Ongoing Maintenance
Scheduled cleaning and inspection appointments help keep custom builds performing exactly as intended, season after season.
Build Records On File
We keep detailed specification and service records for every project, so future adjustments or repairs never start from scratch.
Direct Access To Your Gunsmith
Questions after delivery go straight to the technician who worked on your build, not a generic support queue.

What To Expect When You Visit
Our Denver facility on East Jefferson Drive combines a consultation showroom with a dedicated gunsmithing workshop. Walk-ins are always welcome during business hours, though we recommend booking an appointment for custom build consultations or optics fitting sessions so a specialist is available to give you their full attention.
Please bring a valid, government-issued photo ID for any visit that may involve a firearms transaction, transfer pickup, or service drop-off, as required by federal and Colorado law.
You Don't Have To Live In Denver To Work With Us
A meaningful share of our custom build and gunsmithing clients live outside Colorado. We handle these relationships through phone and video consultations, detailed photo and specification documentation throughout a build, and compliant shipping to a licensed dealer near you for final pickup.
If you're shipping a firearm to us for service, our team will walk you through exactly how to package it, which carrier requirements apply, and how the return shipment will be handled once work is complete — always in accordance with federal and state regulations governing firearm shipment.
