The key benefit is reliable, consistent full-auto functionality at a competitive price point. Since we started stocking this in spring 2025, it’s become one of our steady sellers in this category.

Your Questions Answered
Is this legal to own?
This device is regulated under the National Firearms Act (NFA). It is legal to purchase, but installation and possession on a firearm require prior registration with the ATF as a machine gun, payment of the $200 tax, and receipt of an approved Form 1 or Form 4. Consult with your local FFL/SOT for guidance. We are a licensed retailer and do not provide legal advice.
Why is your price lower than others?
We source directly from vetted manufacturers and maintain lean overhead as a Kansas-based retailer focused on practical parts. We don’t inflate prices with unnecessary marketing. Our staff noted a customer recently drove 3 hours to pick one up instead of waiting for shipping, which speaks to the value we provide.
What’s needed for installation?
Installation requires a compatible Glock pistol, basic armorer’s tools (punches, screwdrivers), and a detailed understanding of the firearm’s internal mechanism. We recommend professional installation by a qualified gunsmith or SOT. The part itself is a drop-in component but must be installed on a registered machine gun receiver.
