G80 Jig Overview
The G80 Jig is a precision finishing tool engineered specifically for the G80 Unfinished Receiver. No modifications, no adapters, no compatibility guesswork. Drop in your receiver, secure the jig, and start working. This is the only jig designed for the G80 platform, and it shows in the fit.
The G80 Jig supports both manual and machine finishing. Use a Dremel with the included grinding stones and drill bits, or mount it in a Ghost Gunner GG3-S for automated milling. Either way, the precision-machined aluminum construction eliminates the walk, chatter, and misalignment that plague universal jigs. Clean cuts, proper pin alignment, professional results.
Unlike disposable jigs bundled with cheaper 80% kits, the G80 Jig is built for repeated use. The tolerances hold build after build, making it the right choice if you’re finishing multiple receivers or helping others complete their builds. Made in USA. Current lead time is 6 weeks. Price: $219.99.
What’s Included with the G80 Jig
1x G80 Jig Hardware Set
2x 3.1mm Drill Bits
1x 4.1mm Drill Bit
1x Grinding Stone (Large)
The included drill bits are specifically sized for the G80’s pin holes. No hunting down third-party bits or adapters. Everything you need to finish your receiver comes in the box.
What Makes the G80 Jig Different
Purpose-Built for G80
The G80 Jig is engineered exclusively for the G80 Unfinished Receiver. Not a universal jig with adapters. Not a polymer frame jig repurposed for steel. The receiver drops in with zero modifications, and the pin hole guides align perfectly with the G80’s specifications. This eliminates the fit issues that cause failed builds with generic jigs.
Manual or Machine Ready
The G80 Jig works with your preferred finishing method. For manual builds, use a Dremel rotary tool with the included grinding stone (recommended cutters: SKU 85602 and 85422). For automated finishing, the jig mounts directly in the Ghost Gunner GG3-S. You can also use a drill press with a 1/4″ end mill for peck-drilling. Same jig, multiple workflows.
Precision-Machined Aluminum
The G80 Jig is CNC-machined from aluminum to tight tolerances. This isn’t injection-molded plastic that flexes under pressure. The rigid construction prevents walk and chatter during milling, and the precision guides ensure your pin holes end up exactly where they need to be. Your finished receiver will have proper alignment for reliable function.
Built for Repeated Use
Disposable jigs lose accuracy after one build. The G80 Jig maintains its tolerances across multiple receivers. If you’re building for yourself, helping friends finish their G80s, or just want tooling that lasts, this jig pays for itself. It’s an investment in your workshop, not a consumable.
VanDerStok Compliance Built In
The G80 system was designed to meet the Supreme Court’s VanDerStok standard, which requires over an hour to complete. Manual finishing with the G80 Jig typically takes 1-2 hours for first-time builders, maintaining compliance while delivering a quality result.

Top-tier jig for serious builders. CNC quality shows, no cheap feel. Used machine config on GG3 — perfect results. Worth it for compliance and precision.

Love how purpose-built this is — no universal hacks, just fits the G80 perfectly. Drill bits were sharp, stones did the job. Finished product feels duty-ready.

Solid jig for the price. Held tolerances tight during grinding and drilling. Some light cleanup on the receiver, but the jig made it straightforward. Will buy again for multiples.

Great for hand-tool users. The guides kept everything aligned, stones handled the material well. Built a duty-grade pistol — feels like a steal at this price.

Precision is insane. Used it on GG3-S setup, and the guides were dead accurate. Included tools saved me from buying extras. Great for anyone wanting a compliant metal FCU build.

This jig is built like a tank. CNC aluminum feels premium, and it guided me through the milling without issues. Paired it with the unfinished receiver — runs great now. Highly recommend.
