G80 Unfinished Receiver

Description

G80 Unfinished Receiver with Pins and Slide Lock Spring

This is where your build starts. The G80 Unfinished Receiver is a precision-machined steel fire control unit — locking block, trigger housing, and slide rails cut from one solid piece of heat-treated 4140 steel giving it extra strength and reliability over the 80% polymer frames of the past. It is fully compatible with GLOCK® 19/23/32 Gen 3 parts. Drop it into your 120R compatible grip module and you’ve got a receiver built to run, not just built to pass.

Compatibility

The G80 includes its own trigger pin, trigger housing pin, and slide lock spring; these replace the corresponding parts from standard GLOCK® lower parts kits.

Why a Steel Fire Control Unit?

Steel fire control units offer several advantages: tighter slide-to-frame fit, zero flex under recoil, virtually unlimited service life, and compatibility with high-round-count training regimens. The monolithic design eliminates the rail alignment issues common with multi-piece polymer frames. For builders prioritizing durability and precision over weight savings, steel is the superior choice.
