AR15 Stripped Upper Receiver
When it comes to building a high-performance, aesthetically striking AR-15, few components make a bigger impact than the receiver set. And for builders who demand both premium quality and eye-catching design, the Gorilla Machining - AR-15 Stripped Upper and Stripped 80% Lower Receiver - FireHouse Red Combo Set is a standout choice. Whether you're assembling your first rifle or upgrading an existing platform, this combo set provides the ideal balance of rugged construction, precision fitment, and bold Cerakote style.
The FireHouse Red Cerakote finish isn’t just for looks—though it certainly turns heads. It also provides a high-temperature, corrosion-resistant coating that enhances the durability and lifespan of your AR-15. Gorilla Machining, a name well-known among firearm enthusiasts and builders, goes the extra mile by applying this finish meticulously to both the stripped upper and the 80% lower receiver. The end result is a cohesive, seamless foundation that’s ready for the builder who refuses to compromise.
With this combo set, you're getting two essential components that work in harmony. The stripped upper receiver is designed to fit seamlessly with most MIL-SPEC components and barrels, while the 80% lower receiver offers builders the flexibility to complete their custom build at home, in accordance with applicable laws. This dual-piece set is engineered with precision to guarantee a tight, secure fit that minimizes play and ensures reliable cycling.
Cerakote has become the gold standard in firearm coatings due to its incredible resistance to abrasion, corrosion, and chemicals. Gorilla Machining takes full advantage of these benefits by offering this combo set in FireHouse Red, a color that screams individuality without sacrificing tactical integrity. Whether you're building a competition rifle, a unique range toy, or a battle-ready tool, this vivid finish adds a custom touch that stands out in any gun safe.
Unlike traditional anodizing, Cerakote adds a ceramic-based coating that not only looks great but also improves overall performance. It reduces wear and tear on contact points, enhances thermal stability, and makes cleaning a breeze. FireHouse Red isn’t just about looks—it's a performance-driven coating for serious shooters and collectors alike.
Gorilla Machining has earned a strong reputation in the AR-building community for its commitment to quality, consistency, and innovation. All of their receivers are CNC-machined from high-grade 7075-T6 aluminum, a material known for its excellent strength-to-weight ratio. This aluminum alloy is the same type used in military-grade weapons systems, offering exceptional durability without unnecessary bulk.
In addition to top-tier materials, Gorilla Machining takes quality control seriously. Each stripped upper and 80% lower is precisely cut to ensure that all parts interface correctly. This eliminates the guesswork and fitment issues that often plague off-brand or poorly manufactured receiver sets. If you're investing time and money into your AR-15, choosing Gorilla Machining means choosing a platform you can trust.
One of the key advantages of this combo set is the inclusion of an 80% lower receiver, giving builders the opportunity to finish the final machining themselves. This appeals to hobbyists, experienced builders, and Second Amendment advocates who value privacy and self-reliance.
By not including the trigger pocket, fire control group pin holes, or other machining features, an 80% lower is not considered a firearm by the ATF. This allows it to be shipped directly to your door in most states without the need for an FFL transfer—though it's important to verify local and federal laws before starting any build.
When paired with Gorilla Machining's stripped upper receiver, the 80% lower offers a seamless aesthetic and mechanical match, simplifying your build process and maximizing compatibility. This combo set is designed to work with all MIL-SPEC AR-15 parts, giving you ultimate flexibility when selecting your bolt carrier group, barrel, handguard, and stock assembly. Whether you’re building a short-barreled pistol configuration or a full-length precision rifle, this set gives you a versatile foundation to build upon.
The stripped upper includes a standard Picatinny top rail, making optics mounting simple and secure. Whether you’re running red dot sights, LPVOs, or iron sights, you’ll get a reliable return-to-zero platform. The lower receiver includes all the specs you need for installing your buffer tube, lower parts kit, and grip of choice once it's fully machined.
When you buy a matched upper and lower combo set—especially from a brand like Gorilla Machining—you’re getting parts that are machined to work together from the start. This ensures:
Tighter tolerances
Better alignment
Reduced rattle or play
Uniform aesthetics (especially with a unique Cerakote color)
Choosing a combo set saves you time, energy, and often money. It also reduces the frustration of dealing with incompatible or mismatched components—something that’s all too common with budget or surplus builds.
A firearm is more than just a tool—it’s a reflection of the builder's vision, personality, and technical skill. The Gorilla Machining - AR-15 Stripped Upper and 80% Lower Combo Set in FireHouse Red empowers that vision with a blend of aesthetic appeal, performance-ready specs, and builder flexibility.
Whether you're planning a themed build or just want to break away from standard black or FDE tones, this red-hot Cerakote finish sets your rifle apart. Pair it with red-anodized accessories or black furniture for a bold contrast that’s equal parts functional and fierce.
The Gorilla Machining - AR-15 Stripped Upper and Stripped 80% Lower Receiver - FireHouse Red Combo Set is more than just an eye-catching set of components—it’s a smart investment in quality, performance, and individuality. With MIL-SPEC compatibility, precision machining, and a rugged Cerakote finish, this combo set gives you everything you need to create a custom AR-15 that performs as well as it looks.
Whether you're building for competition, range use, personal defense, or the sheer joy of creation, Gorilla Machining delivers the foundation you can count on. Add in the legal and DIY appeal of the 80% lower, and you’ve got one of the best value options on the market today.
