What You’ll Need to Complete Your Build
The G80 Build Kit gives you the foundation. Here’s what else you’ll source to finish your pistol.
G80 Build Kit FAQ
The G80 Build Kit includes three components: the G80 Unfinished Receiver (steel FCU with pins and slide lock spring), the G80 Jig (with grinding stones and drill bits), and the G80 Grip Module in your choice of color. Together, these form the complete foundation for your G80 pistol build.
The Build Kit provides the G80-specific components, but you’ll still need a few additional parts to complete your pistol: a G19 Gen3 slide assembly (or slide, barrel, and recoil spring separately), a lower parts kit, magazines, and finishing tools (Dremel for Manual jig or Ghost Gunner GG3-S for Machine jig). All of these are widely available from aftermarket suppliers.
The Build Kit is priced below the combined retail of all three components purchased individually. Exact savings depend on your grip module color selection, but every kit configuration offers a discount compared to separate purchases, plus you get everything in one shipment.
Yes. The G80 system was designed specifically to comply with the VanDerStok standard established by the Supreme Court in March 2025. The kit ships without all necessary components, requires uncommon tools, and takes over an hour to complete. Meeting all three criteria for federal legality. Note: G80 does not ship to states that have banned privately made firearms.
The G80 accepts any OEM or aftermarket Glock G19, G23, or G32 Gen3 components. This includes complete slides, barrels, recoil springs, and frame parts kits. Gen3 through Gen5 magazines are all compatible. 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.
Absolutely. The G80 uses the 120R grip module standard, so your finished receiver can drop into any 120R-compatible grip. Buy additional colors from G80, or explore the open-source 120R ecosystem to 3D print custom grips. Your serialized receiver stays the same, only the grip module changes.
Steel fire control units offer superior durability, tighter slide-to-frame fit, zero flex under recoil, and virtually unlimited service life. The G80’s monolithic design eliminates the rail alignment issues common with multi-piece polymer frames. For builders who prioritize long-term reliability and precision over weight savings, steel is the clear choice.
Lead times vary based on component availability. Check the product page above for current stock status on each item in the kit. If any component shows limited availability, consider ordering soon, G80 products move fast and restocks can take time.
Under current federal law, privately made firearms built for personal use do not require serialization. However, state laws vary significantly, some require serialization of all PMFs, others prohibit unfinished receivers entirely. G80 does not ship to restricted states. Always verify your local regulations before purchasing.
