G80 Polymer Jig Build Kit w/ Matador Arms Grip Module

Description

G80 Polymer Jig Build Kit w/ Matador Arms Grip Module [Receiver + Matador Grip + Polymer Jig]

Everything you need to go from raw steel to finished FCU, in one box — now with the aggressive Matador Arms grip. The G80 Build Kit pairs the unfinished receiver with the polymer clamshell jig and a Matador Arms grip module, all engineered to work together, so you’re not chasing down compatibility issues or sourcing parts from three different vendors. The grip brings faceted texture, a high beavertail, a deeply undercut trigger guard, and an integrated flared magwell to your build. Your finished receiver drops in and pins in place like any other 120R module. Each component is proudly made in the USA.

Compatibility

The Matador Arms G80 Grip Module in this kit is compatible with GLOCK® G19, G23, and G32 Gen 3 slide assemblies, standard GLOCK® Gen 3 lower parts kits (LPKs), and GLOCK® Gen 3 – Gen 5 magazines.

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.
