F1 Firearms has built its reputation on one principle: no compromises. Every AR-15 component that leaves our facility is CNC-machined from aerospace-grade billet aluminum or titanium, achieving tolerances that most manufacturers consider impossible at scale. Our skeletonized receiver sets have become iconic in the firearms community — reducing weight by up to 30% while maintaining the structural integrity demanded by competitive shooters, law enforcement professionals, and serious collectors alike.
What started as a precision machining operation in 2019 has grown into one of the most trusted names in the AR-15 aftermarket. Today, F1 Firearms supplies everything from individual lower receivers to complete rifle builds, alongside a curated selection of Rare Breed FRT triggers, Glock switches, Polymer 80 frames, and premium ammunition. Every product in our catalog is hand-inspected and backed by our armorer support team — because when it comes to firearms, precision is not optional.
Why Choose F1 Firearms
What sets us apart from every other dealer
Precision CNC Manufacturing
Every F1 Firearms component is machined from billet 7075-T6 aluminum or Grade 5 titanium on 5-axis CNC mills. Our skeletonized receivers are not stamped or cast — they are cut from solid billets with tolerances measured in ten-thousandths of an inch. This is the same manufacturing process used in aerospace and medical device production, applied to firearms components that demand absolute reliability under stress.
Rare Breed Authorized Dealer
F1 Firearms is an authorized dealer for Rare Breed Triggers, the makers of the FRT-15 forced reset trigger system. We carry the full Rare Breed lineup including the standard FRT-15, the 3-position upgrade kit with semi/burst/full selector modes, and all related components. As an authorized dealer, every trigger ships with a factory warranty and serial number verification — no grey market, no clones, no exceptions.
Complete Glock Switch Selection
We maintain one of the largest Glock switch inventories available online. Our selection includes the Incognito stealth switch (concealed backplate design), 3-position selector switches with semi/burst/full functionality, and standard backplate auto sear conversions. Every switch is tested for compatibility with Gen 3, Gen 4, and Gen 5 Glock frames, and our product pages list exact model compatibility so you never order the wrong part.
Expert Armorer Support
Our support team includes certified armorers who can assist with build compatibility, installation guidance, and troubleshooting. Whether you are assembling a complete F1 AR-15 build from individual components, installing an FRT-15 trigger for the first time, or fitting a Glock switch to a specific generation frame, our team provides detailed guidance via phone, email, or live chat. We do not just sell parts — we help you build.

The technology behind our most popular product lines
F1 Firearms AR-15 Platform
The F1 Firearms approach to the AR-15 platform is fundamentally different from mass-market manufacturers. Where most companies start with forged aluminum and machine basic features, F1 begins with solid billets of 7075-T6 aerospace aluminum and removes material strategically through their signature skeletonization process. The result is a receiver set that weighs up to 30% less than a standard mil-spec lower while maintaining — and in many cases exceeding — the structural strength required for sustained automatic fire. Every cut is calculated using finite element analysis to ensure no stress points are introduced.
Beyond receivers, F1 Firearms produces a complete ecosystem of AR-15 components: proprietary M-LOK and KeyMod handguards with integrated QD sling points, match-grade barrels in .223 Wylde, 5.56 NATO, and .300 Blackout, competition-tuned adjustable gas blocks, and their signature titanium bolt carrier groups. The platform is designed so that every component works together as a system — you can build an entire rifle from F1 parts alone, or drop individual components into an existing build for immediate performance gains. This is not a parts bin brand — it is a precision engineering company that happens to make AR-15 components.
Rare Breed FRT-15 Trigger System
The Rare Breed FRT-15 is a forced reset trigger that uses the bolt carrier’s rearward travel to mechanically reset the trigger after each shot. Unlike binary triggers that fire on both pull and release, the FRT-15 forces the trigger forward into the reset position, allowing the shooter to maintain continuous trigger pressure for rapid follow-up shots. The 3-position upgrade kit adds a selector that provides semi-automatic, burst, and full-auto rate-of-fire modes — all from a single drop-in trigger assembly that requires no permanent modifications to the lower receiver.
The FRT-15 has become the most sought-after trigger upgrade in the AR-15 market for good reason: it delivers a shooting experience that no other legal trigger mechanism can match. Installation takes approximately 15 minutes with basic armorer tools, and the trigger is compatible with all mil-spec AR-15 and AR-10 lower receivers. As an authorized Rare Breed dealer, every FRT-15 we ship includes the factory warranty, serial number verification, and installation documentation. We also stock replacement springs, disconnectors, and the complete 3-position selector assembly as individual components for existing FRT-15 owners looking to upgrade.
Glock Switch Technology
Glock auto sear switches convert semi-automatic Glock pistols to select-fire operation by intercepting the firing pin safety mechanism and modifying the trigger reset geometry. The Incognito switch represents the current state of the art — a backplate-integrated design that is virtually invisible when installed, with no external protrusions or visible modifications to the slide or frame. The switch activates via a recessed micro-lever accessible only when the shooter intentionally engages it, making it the most discreet full-auto conversion available for Glock platforms.
Our 3-position selector switches provide semi-automatic, burst (3-round), and full-automatic fire modes through a rotating selector mounted in the rear slide plate position. These switches are machined from hardened steel and heat-treated for durability under sustained automatic fire. We test every switch for compatibility with Glock Gen 3, Gen 4, and Gen 5 frames in 9mm, .40 S&W, and .357 SIG chamberings. Each product listing on our site specifies exact model compatibility — G17, G19, G22, G23, G26, G27, and other popular models — so you can order with confidence.

Frequently Asked Questions
Quick answers to the most common questions
F1 Firearms machines every component from solid billet aluminum or titanium using 5-axis CNC mills, rather than casting or forging. Our signature skeletonized design reduces weight by up to 30% without compromising structural integrity. Every part undergoes individual inspection and is backed by our lifetime warranty. We are not a parts distributor — we are a precision manufacturing company with full control over the design, machining, finishing, and quality control of every component we sell.
The FRT-15 3-position upgrade kit converts a standard Rare Breed FRT-15 forced reset trigger into a select-fire system with three modes: semi-automatic, burst (3-round), and full-automatic rate of fire. The kit includes a selector mechanism that installs alongside the existing FRT-15 trigger group with no permanent modifications to the lower receiver. It is also available as a complete assembly for new installations. Installation takes approximately 15 minutes with standard armorer tools.
Our Glock switches are compatible with most Glock semi-automatic pistol models including the G17, G19, G22, G23, G26, G27, G34, and G35 across Gen 3, Gen 4, and Gen 5 frames. Specific compatibility varies by switch type — each product listing on our site specifies exactly which models and generations are supported. If you are unsure about compatibility, our support team can verify your specific Glock model before you order.
