KIGER-9C FDE
About this product
The KIGER-9C FDE is a compact, FDE-finished polymer frame for the 9mm AR platform designed specifically to accept Glock magazines. This is our direct-from-factory final production run, offering shooters a rare opportunity to acquire a component we are sunsetting. It serves as the dedicated lower receiver platform for building ultra-reliable, magazine-interchangeable PCCs and PDWs.
What is the KIGER-9C FDE used for?
The KIGER-9C FDE is used for building a compact 9mm AR-pattern pistol or pistol-caliber carbine that feeds from proprietary Glock magazines. Builders achieve two primary goals: gaining Glock magazine commonality across platforms and creating a lightweight, maneuverable firearm for home defense or competition. The FDE finish provides a tactical aesthetic with reduced visual signature in certain environments.
How does the KIGER-9C FDE compare to the Polymer80 PF940V2?
The KIGER-9C FDE is better for dedicated rifle-format builds using an AR-15 upper, while the Polymer80 PF940V2 is better for constructing a traditional Glock-style pistol. Our frame requires a complete AR-15 lower parts kit and is compatible with standard AR-15 triggers, unlike the Polymer80 which uses Glock OEM or aftermarket Glock components. The KIGER platform offers superior ergonomic customization via the AR-15 grip and stock/brace ecosystem.
What does it weigh and what are the dimensions?
The stripped KIGER-9C FDE frame weighs 14.2 ounces (402 grams) and measures 7.8 inches in length from the rear of the buffer tube threads to the front of the magazine well. The magazine well opening is specifically machined to 1.18 inches wide to ensure smooth Glock magazine insertion and drop-free release. This contrasts with the heavier, all-aluminum alternatives that typically weigh over 24 ounces.
Who is this NOT for?
This frame is NOT for first-time builders or anyone unfamiliar with assembling an AR-15 lower receiver from parts. It requires technical skill, proper tools like roll pin punches and an armorer's wrench, and about 45-60 minutes of focused assembly time. If you want a drop-in-ready firearm, consider a complete pistol like a Glock 19 or a factory-built AR-9 from a company like Foxtrot Mike.
What's in the box?
You receive the complete, FDE-finished KIGER-9C polymer frame, the magazine catch assembly, and the bolt catch assembly—these are the only proprietary parts. The box does NOT include a lower parts kit, buffer system, stock/brace, or an upper receiver. You will need to source a standard AR-15 lower parts kit, including an appropriate trigger like our Glock-Mod 3.5lb Connector, to complete the build.
Is the KIGER-9C FDE worth it at $300?
At $300, the KIGER-9C FDE offers significant value for a shooter committed to the Glock magazine ecosystem in an AR platform, especially as a final-run product. It saves you the $80-$150 typically required for a dedicated Glock magazine adapter block on a standard AR lower. Compared to a competing milled aluminum frame costing $450+, you invest the $150 savings into a better barrel or optic. This is a buy-once component for a professional-grade tool.

Pros & cons
What works
- Weighs 14.2 oz — 10 oz lighter than typical milled aluminum AR-9 lowers.
- Accepts all Glock double-stack 9mm magazines for unmatched parts commonality.
- Uses standard AR-15 lower parts kits — no proprietary small parts required.
- FDE Cerakote finish applied — more durable than standard polymer anodizing.
- Final production run — possesses inherent collectibility for platform enthusiasts.
Trade-offs
- Requires full lower assembly — not a drop-in option for beginners (45-60 min build time).
- Proprietary mag and bolt catches — replacements must be sourced directly from GLOCK FRT.
- No included tensioning screw for upper/lower fit — may require accuwedge for zero play.
- Final sale, no returns — due to sunsetting production, all sales are absolute.
- Polymer construction — not recommended for sustained full-auto fire or .40 S&W conversions.

Frequently asked questions
- Is the KIGER-9C FDE compatible with Gen 5 Glock magazines?
- Yes, it is fully compatible with all double-stack 9mm Glock magazines, including Gen 5 models (G17, G19, etc.). The magazine well is machined to accept the universal Glock magazine lip design. We tested with OEM Glock, Magpul PMAG GL9, and ETS magazines with zero feed issues after proper break-in.
- Does the KIGER-9C FDE fit a standard AR-15 jig for drilling?
- No. The KIGER-9C FDE comes as a fully finished, serialized frame, not an 80% lower. It requires no drilling or milling. It is ready for immediate installation of a standard AR-15 lower parts kit. This distinguishes it from unserialized polymer blanks which require significant tooling and a dedicated jig.
- How long does shipping take once I order?
- All orders ship within 2-3 business days via UPS or FedEx with adult signature required. Transit time is typically 3-5 business days within the continental United States. International orders and shipments to restricted states (CA, NY, etc.) are not accepted due to final sale status and regulatory complexity.
- Can I return it if it doesn't fit my upper receiver?
- No. This is a final sale item with no returns or exchanges, as stated clearly on the product page at time of purchase. We strongly recommend verifying your planned upper receiver's compatibility with Glock-magazine lower platforms before ordering. Most dedicated AR-9 uppers from manufacturers like CMMG, Foxtrot Mike, and PSA will mate correctly.
- Does this work with a binary trigger like a Franklin Armory BFSIII?
- Potentially, but it is not guaranteed or endorsed. The KIGER-9C uses a standard AR-15 fire control group pocket. Mechanical function with a binary trigger depends entirely on your selected upper receiver's bolt carrier group timing and hammer engagement. We recommend starting with a proven mil-spec or enhanced single-stage trigger like our Glock-Mod offerings for reliability.
