Building Your Polymer 80 Glock Takes a Single Afternoon!

Building your Polymer 80 Glock takes a single afternoon. All you need to complete your Frame is the provided tooling, a hand drill, and some hand files. Completing your Polymer80 frame is as simple as drilling a few holes and removing some excessive polymer using a mill or hand files. No experience is necessary and we provide plenty of instructions and tutorials to guide you along!

Is Building a Glock at Home Legal?

Your Polymer 80 Glock Frame and Jig Kit is not legally considered a firearm! That means your kit ships directly to your front door – and no FFL or paperwork is required to build your new Glock at home.

Because we’re not considered an FFL, we don’t include added costs or fees in any of our Polymer 80 kits – we pass those savings on to you. Because your kit isn’t considered a firearm, there’s no need to deal with additional fees, waiting periods, or higher tax rates! Once you receive your kit, you can start building immediately.

Some states require serialization before building, so check your local laws first.

More Glock Stuff Coming Soon!

We’re constantly expanding our available build-a-gun kits and components. Check back soon for more Polymer 80 frames, and keep your eyes peeled for upcoming slides, Glock parts kits, and accessories!
