BUSHMASTER® BRAVO ZULU™ BFSIII® GOREADY™ KIT

The Bushmaster Bravo Zulu BFSIII Goready Kit offers Tennessee shooters a unique opportunity to streamline your AR-platform rifle experience by combining binary firing capability with a complete recoil system upgrade. Whether you’re on a private range outside Nashville or testing loads at a club near Knoxville, this kit provides a reliable way to explore enhanced firing modes without requiring a full firearm purchase. For Tennessee residents who value both precision and efficiency, this kit represents a practical upgrade path for existing builds.

What This Product Is and Who It’s For

The Bushmaster Bravo Zulu BFSIII Goready Kit is a drop-in conversion and recoil system package designed for AR-platform rifles chambered in 5.56 NATO or .223 Remington. It integrates Franklin Armory’s BFSIII binary firing system with Bushmaster’s Goready recoil management components. This kit is intended for responsible firearm owners who want to expand their shooting experience without modifying their lower receiver or purchasing a new firearm. Target shooters will appreciate the binary mode for rapid, controlled strings of fire, while home defense users can retain the standard semi-automatic mode for conventional operation. Collectors and enthusiasts who value modularity will find this kit a straightforward addition to their inventory. This product is not recommended for first-time AR builders or those unfamiliar with firearm safety protocols regarding firing modes.

Feature Deep-Dive

The BFSIII binary firing system is the centerpiece of this kit, allowing the firearm to fire one round on the pull of the trigger and a second round on the release. This mode is distinct from full-automatic fire, as it requires deliberate trigger manipulation for each shot cycle. The system uses a modified hammer, sear, and disconnector that interface with a three-position safety selector. When in binary mode, the shooter can achieve rapid follow-up shots while maintaining control over the firing cadence. The mechanism is engineered to work with standard AR-15 fire control group pockets, meaning no permanent modifications to the lower receiver are necessary.

The Goready recoil system included in this kit is designed to reduce muzzle rise and felt recoil during rapid fire. It consists of a weighted buffer and a progressive spring assembly that absorbs and redirects energy more efficiently than standard mil-spec components. This is particularly useful when using the binary firing mode, as the reduced recoil impulse helps maintain sight picture and target acquisition. The buffer weight is optimized for 5.56 NATO loads but functions reliably with .223 Remington ammunition. Installation requires basic AR-15 disassembly knowledge, and the kit includes all necessary springs and pins.

The ambidextrous safety selector is a notable inclusion, providing left-handed shooters with equal access to the three firing modes. The selector is clearly marked with “Safe,” “Semi,” and “Binary” positions, and the detents are positive and audible. This selector is machined from billet aluminum and is compatible with most aftermarket lower receiver parts. The kit also includes a detailed instruction manual that covers installation, function check procedures, and safety guidelines specific to binary operation. Users should familiarize themselves with these instructions before installation to ensure proper function.

Durability testing on the BFSIII system has shown reliable performance across a range of ammunition types, including 55-grain and 62-grain loads. The hammer and sear surfaces are case-hardened to resist wear from extended use. The Goready buffer assembly is constructed from 4140 steel and is finished with a corrosion-resistant coating. The kit is designed to function in both standard and piston-driven AR-15 configurations, provided the lower receiver is mil-spec. Users with non-standard lower receivers (e.g., polymer or billet with tight tolerances) should verify compatibility before purchase.

One practical advantage of this kit is that it does not require a tax stamp or NFA registration, as the binary firing system is classified as a semi-automatic trigger modification. This makes it accessible to Tennessee residents who are legally allowed to own standard AR-15 rifles. The kit ships as a collection of components, not as a complete firearm, so it can be shipped directly to your door in most cases. However, local laws regarding trigger modifications should be reviewed before ordering. The kit is designed for use with standard AR-15 magazines, including those from Magpul, Lancer, and GI-style manufacturers.

Ideal Use Cases

This kit is well-suited for range shooting and target practice, particularly for shooters who want to explore binary firing in a controlled environment. The reduced recoil from the Goready system makes it easier to stay on target during rapid strings, which can improve accuracy drills. Home defense use is possible in semi-auto mode, but the binary mode should only be employed in scenarios where rapid fire is legally justified and safe. Hunting applications are limited, as binary firing is not typically used for game taking; however, the semi-auto mode functions normally for varmint or predator control. Competition shooters in disciplines that allow binary triggers may find this kit useful for speed events, though most competitive organizations restrict firing modes to semi-automatic only.

Compatibility Notes

• Ammunition: This kit functions with all standard 5.56 NATO and .223 Remington ammunition, including brass-cased, steel-cased, and aluminum-cased loads. For best reliability, use ammunition with consistent primer seating and bullet weight between 55 and 77 grains. Avoid using reloaded ammunition with soft primers or inconsistent powder charges, as binary firing can reveal timing issues.
• Holsters: Not applicable; this is a trigger and recoil kit for a rifle platform, not a handgun.
• Magazines: Compatible with all standard AR-15 magazines, including 10-round, 20-round, and 30-round capacities. Drum magazines may function but are not recommended for binary mode due to potential feeding issues at high cyclic rates.
• Accessories: This kit works with most AR-15 aftermarket grips, stocks, and handguards. The safety selector is compatible with standard 45-degree and 90-degree throw selectors, though the included selector is designed for 90-degree throw. The Goready buffer is compatible with carbine-length buffer tubes; rifle-length tubes will require a different buffer setup.

Frequently Asked Questions

Q: Can this kit be shipped directly to my home in Tennessee?
A: Yes, because the Bushmaster Bravo Zulu BFSIII Goready Kit is not a complete firearm, it can be shipped directly to your residential or business address in Tennessee. No FFL transfer is required for the kit itself. However, you must be at least 18 years old and legally allowed to own firearm components in your jurisdiction. We ship via UPS or FedEx with adult signature required.

Q: Do I need to go through an FFL transfer for this kit?
A: No, an FFL transfer is not required because this kit consists of trigger components and a buffer system, not a receiver or complete firearm. However, if you are installing this kit into a lower receiver that you do not already own, you will need to acquire that lower receiver through a standard FFL transfer. The kit itself ships without additional paperwork.

Q: What ammunition is recommended for binary firing with this kit?
A: We recommend using factory-new 5.56 NATO ammunition with a bullet weight of 55 to 62 grains for best performance in binary mode. Avoid using .223 Remington ammunition loaded to lower pressure levels, as binary firing can cause cycling issues with underpowered loads. Steel-cased ammunition may function but can increase wear on the trigger components over time. Always test a small batch of your chosen ammunition in semi-auto mode before switching to binary.

Q: What warranty is included with this kit?
A: Bushmaster offers a limited lifetime warranty to the original purchaser against defects in materials and workmanship. This warranty covers the BFSIII trigger group and Goready recoil system components. The warranty does not cover damage from improper installation, use of incorrect ammunition, or modifications to the kit. Claims must be submitted through Bushmaster’s customer service portal with proof of purchase. We recommend retaining your receipt and registering the product online.

Q: What is your return policy for this item?
A: We accept returns of unopened and unused kits within 30 days of delivery for a full refund minus shipping costs. Once the kit has been installed or shows signs of use, it cannot be returned due to safety and liability reasons. If you receive a damaged or defective kit, contact us within 48 hours of delivery for a replacement or exchange. All returns require an RMA number obtained through our customer service team.
