AR15 Threaded Stripped Receiver Set – OD Green Cerakote

Description

For U.S. gun owners who value precision and durability, the AR-15 platform remains one of the most versatile firearms for sport, defense, and hunting. Whether you’re a first-time builder or an experienced enthusiast, starting with a reliable stripped receiver set is the foundation of a dependable rifle. The Aero Precision Stripped Receiver Set in OD Green Cerakote offers a robust starting point for a custom build that meets your specific needs without unnecessary frills.

What This Product Is and Who It’s For

This product is a stripped receiver set, meaning it includes the upper and lower receivers without internal components such as the bolt carrier group, charging handle, trigger group, or stock. It is designed for individuals who want to assemble their own AR-15 from the ground up, selecting each part to match their intended use. This set is suitable for target shooters who want a reliable range rifle, home defense owners looking for a custom configuration, hunters who prefer a lightweight and accurate build, and collectors who appreciate a clean, factory-finished platform. The OD Green Cerakote finish adds a layer of protection and a distinctive appearance without compromising functionality.

Feature Deep-Dive

The Aero Precision stripped receiver set is built from 7075-T6 aluminum, a material chosen for its strength-to-weight ratio and resistance to fatigue. Forged receivers are denser and more consistent than cast alternatives, which translates to tighter tolerances and better alignment during assembly. This is particularly important for builders who want to avoid common issues like misaligned trigger pin holes or loose upper-to-lower fitment. The OD Green Cerakote finish is applied using a multi-step process that bonds to the metal, providing a hard, scratch-resistant surface that holds up to regular handling and exposure to solvents.

The upper receiver features a forward assist and ejection port cover, both standard for mil-spec builds. The Picatinny rail is machined as part of the upper, offering a solid mounting surface for optics, red dots, or backup iron sights. The lower receiver includes a flared magazine well for easier reloads under stress, and the trigger guard is integrated into the lower, eliminating the need for a separate trigger guard pin. The grip angle is standard mil-spec, but you can replace it with any aftermarket grip that fits AR-15 lowers. The receiver set is marked “Multi” for caliber, meaning it can accommodate not only 5.56 and .223 but also other calibers with appropriate barrel and bolt changes, such as 300 Blackout or 6.5 Grendel.

One of the standout features of this Aero Precision set is the tensioning screw in the lower receiver. This small set screw allows you to adjust the fit between the upper and lower receivers, reducing wobble and improving accuracy potential. While not necessary for function, many builders appreciate the ability to fine-tune the fit for a more solid feel. The receiver set also uses a standard mil-spec buffer tube thread pattern, so you can install any commercial or mil-spec stock system without modifications. The bolt catch and magazine release are standard dimensions, making replacements or upgrades straightforward.

The OD Green Cerakote finish is not just for looks. Cerakote is a ceramic-based coating that provides excellent resistance to corrosion, chemicals, and abrasion. This is especially valuable for firearms used in humid environments, such as coastal states or during rainy hunting seasons. The finish is also non-reflective, which can be an advantage for hunters or shooters who prefer a low-visibility profile. Unlike some painted finishes, Cerakote does not chip easily and maintains its color even after repeated cleaning with solvents like CLP or brake cleaner.

For builders who plan to use this receiver set for home defense or competition, the compatibility with standard AR-15 parts means you can source components from a wide range of manufacturers. The lower receiver accepts any mil-spec trigger group, from single-stage to two-stage, and the upper receiver works with any standard barrel nut and handguard system. This flexibility allows you to build a rifle that matches your budget and performance requirements without being locked into proprietary parts. The receiver set is also compatible with most aftermarket ambidextrous controls, such as safety selectors and magazine releases, if you prefer a left-handed or ambidextrous setup.

Finally, the receiver set is marked with a serial number on the lower receiver, which is required for federal firearms registration. This is a critical detail for legal ownership and transfer. The upper receiver is not serialized and can be purchased and shipped directly to your door, but the lower receiver must be shipped to a Federal Firearms License (FFL) dealer for transfer. Aero Precision is known for consistent quality control, and each receiver set is inspected before leaving the factory, reducing the likelihood of out-of-spec dimensions that can cause assembly headaches.

Ideal Use Cases

This stripped receiver set is best suited for building a rifle for target shooting at the range, home defense, or hunting medium game with appropriate caliber choices. For target shooters, the ability to select a match-grade barrel and trigger makes this a solid foundation for precision work. Home defense builds benefit from the reliability of mil-spec parts and the option to use a shorter barrel with a pistol brace or stock. Hunters can pair this receiver set with a lightweight barrel and a caliber like .300 Blackout for deer or hogs. It is less suited for concealed carry due to the size of the AR-15 platform, but it can be built as a pistol configuration with a brace for vehicle or bedside use. Competition shooters in three-gun or tactical matches will appreciate the compatibility with drop-in triggers and free-float handguards.

Compatibility Notes

• Ammo: For 5.56 NATO and .223 Remington barrels, use standard .223 or 5.56 ammunition. For caliber swaps, ensure barrel and bolt are matched (e.g., 300 Blackout uses the same bolt but different barrel).
• Holsters: Not applicable for a stripped receiver set; holsters are for completed firearms. Once built, consider a sling or case for transport.
• Magazines: Accepts all standard AR-15 magazines, including Magpul PMAG, Lancer, and aluminum GI magazines. Check local capacity laws.
• Accessories: Compatible with mil-spec buffer tubes, stocks, pistol braces, handguards, grips, triggers, and optics. Avoid proprietary parts unless specifically designed for Aero Precision receivers.

FAQ Section

1. How does shipping work for this receiver set?
We ship to all 50 U.S. states, but the lower receiver must be sent to a licensed FFL dealer for transfer. The upper receiver can be shipped directly to your home address. We require a copy of your FFL’s license before shipping the lower. Standard shipping rates apply, and we use carriers that require an adult signature upon delivery.

2. What is the FFL transfer process?
After placing your order, we will contact you to confirm your chosen FFL dealer. You must provide their name, address, and license number. We verify the FFL and ship the lower receiver to them. You then visit the dealer, complete a Form 4473, and pass a background check (where required) to take possession. Fees for the transfer are set by the dealer and are not included in our price.

3. What ammunition is compatible with this receiver set?
Since this is a stripped receiver set, it does not have a barrel or bolt. Once built with a 5.56 NATO or .223 Remington barrel, it will accept both .223 and 5.56 ammunition. For other calibers, ensure the barrel and bolt are designed for that specific round. Do not use ammunition that exceeds the pressure rating of your barrel.

4. Does this product come with a warranty?
Yes, Aero Precision provides a limited lifetime warranty against defects in materials and workmanship for the original purchaser. This covers issues like cracks or out-of-spec dimensions but does not cover damage from misuse, modification, or improper assembly. We recommend contacting Aero Precision directly for warranty claims, though we can assist with the process.

5. What is your return policy for this item?
We accept returns on unused, unmodified receiver sets within 30 days of delivery. The item must be in its original packaging with all parts. Because this is a firearm component, we cannot accept returns on assembled or altered receivers. A restocking fee may apply. Contact our customer service team for a return authorization before shipping.
