G80 Jig

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.

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.
