G80 Build Kit

The G80 Build Kit puts the core G80 components together in one package, giving you a matched receiver, jig system, and grip module without having to source each piece separately.

Designed around the G80 modular platform, the kit combines steel construction at the receiver with a replaceable polymer grip module. Each component is engineered as part of the same system, helping eliminate the fitment issues that can come with mixing unrelated components.

All three primary components are manufactured in the USA.

Included in the G80 Build Kit

G80 Unfinished Receiver

The central component of the G80 platform is a precision-machined steel receiver manufactured from heat-treated 4140 steel and finished in black nitride.

Unlike traditional polymer-frame designs, the G80 system places the core structural components into a steel receiver that interfaces with the removable grip module.

Features:

• Heat-treated 4140 steel construction
• Black nitride finish
• G19 Gen 3 component compatibility
• Integrated slide rails
• Integrated locking block
• Captive trigger housing design
• Integrated slide-lock system
• Compatible with 120R-pattern grip modules

G80 Polymer Jig

The included polymer jig is designed specifically around the G80 receiver platform.

Steel drill bushings are molded into the jig at the designated locations, while steel dowel pins provide repeatable receiver positioning. The combination gives the jig added rigidity and durability while keeping the system lighter and more affordable than an all-metal fixture.

Features:

• Injection-molded construction
• Embedded steel bushings
• Steel dowel-pin registration
• Reusable design
• Rotary and drill bits included
• Reduced heat transfer compared with metal fixtures
• Designed specifically for the G80 receiver

G80 Grip Module

The G80 grip module provides the ergonomic exterior of the finished G80 platform while allowing the steel receiver assembly to remain independent from the grip itself.

Its modular design allows compatible grip modules to be changed without replacing the central steel receiver.

Features:

• Reinforced polymer construction
• 120R-pattern compatibility
• Ergonomic grip geometry
• Drop-in receiver interface
• Multiple color options
• Replaceable and customizable design
• Compatible with the broader 120R ecosystem

Why Choose the Complete G80 Kit?

Matched Components

The receiver, jig, and grip module are designed around the same G80 platform, reducing uncertainty about component compatibility.

Better Bundle Value

Buying the complete kit packages the primary G80 components together rather than purchasing each piece individually.

One Complete Package

The major G80 platform components arrive together in a single order, simplifying purchasing and shipping.

Modular Steel Receiver Design

The G80 platform combines a heat-treated steel receiver with a replaceable polymer grip module, creating a substantially different architecture from traditional one-piece polymer-frame designs.

G80 Build Kit Includes

• 1 G80 Unfinished Steel Receiver
• 1 G80 Polymer Jig
• 1 G80 Grip Module
• Included manufacturer-supplied jig tooling
