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 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.

G80 Jig FAQ

Frequently Asked Questions

Is the G80 Jig reusable?

Yes. The G80 Jig is precision-machined from aluminum and designed for repeated use. Unlike disposable plastic jigs included with cheaper 80% kits, it maintains tolerances across multiple builds. If you’re finishing more than one G80 receiver, this jig pays for itself.

How long does it take to finish a G80 receiver with the G80 Jig?

Manual finishing with a Dremel typically takes 1-2 hours for first-time builders. Machine finishing with a GG3-S is faster. This completion time also maintains compliance with the VanDerStok standard, which requires over an hour to complete.

Will the G80 Jig work with Polymer80 or other 80% frames?

No. The G80 Jig is engineered exclusively for the G80 Unfinished Receiver, which is a heat-treated steel FCU. It will not work with Polymer80, GST-9, or any other 80% platform. This purpose-built design eliminates fit issues and ensures proper pin alignment.

What’s included with the G80 Jig?

The G80 Jig hardware set, two 3.1mm drill bits, one 4.1mm drill bit, and a large grinding stone. The drill bits are specifically sized for G80 pin holes. No additional accessories required.

Can I use a drill press instead of a Dremel with the G80 Jig?

Yes. Many builders use a drill press with a 1/4″ end mill to peck-drill the metal obstructions. The G80 Jig’s precision machining ensures consistent results whether you use a drill press, Dremel, or GG3-S. Choose whichever method matches your workshop setup.

Why does the G80 Jig cost more than jigs included with other 80% kits?

You’re investing in precision tooling, not a disposable piece of plastic. The G80 Jig is CNC-machined to tight tolerances that prevent walk, chatter, and misalignment. It’s designed for repeated use across multiple receivers, making it more economical per-build than single-use alternatives.

What Glock parts work with a completed G80?

Once finished, the G80 receiver accepts any OEM or aftermarket Glock G19, G23, or G32 Gen3 components: complete slides, frame parts kits, and Gen3-Gen5 magazines. The G80 includes its own pins and slide lock spring that replace corresponding parts from standard Glock LPKs.
