Frequently Asked Questions

Need help with an order, shipping update, product compatibility, return, warranty claim, or showroom visit? Start here.

Order Status & Shipping

What is the status of my order? Where is my tracking number?

Once your order has been processed and shipped, you will receive an automated email containing your tracking number. If you have not received an update, please check your spam or promotions folder.

During high-volume periods, sales, or regulatory changes, processing times may be longer than normal.

What does “Manual Verification Required” mean?

Manual Verification Required is a standard payment security review. In some cases, our team may need to verify the payment method used before the order can continue processing.

No action is required unless our support team contacts you directly.

What are your current lead times?

Lead times can vary depending on order volume, product availability, and current demand. Orders containing high-demand items, including jigs, may take longer to process.

Our team is working to process all orders as quickly as possible, and tracking will be sent automatically once your order ships.

Can I change my shipping address after placing an order?

Address changes can only be made if the order has not entered the fulfillment process. If you need to update your address, contact support immediately with your order number.

Once a tracking number has been generated, we are unable to reroute the package.

Technical & Product Support

Is the GST-9 compatible with my components?

The GST-9 MOD100 frame is designed for modularity and is compatible with Gen 3 Glock-style components. Depending on the configuration, it can be used with Glock 19 or Glock 17 length slides with the appropriate extensions.

Will the Easy Jig work with my router?

The Easy Jig Gen 3 is a multi-platform jig designed for AR-15, AR-9, and .308 lowers. Router compatibility can vary, so always check your router and tool kit specifications before beginning.

Where can I find installation instructions or manuals?

Digital PDF manuals and installation instructions are available above on this page. If you cannot find the correct manual or your physical instructions are missing, contact support and we can help provide the latest version.

Do I need an FFL to order your products?

Many 80% products and jigs can ship directly to your home where legally permitted. Completed frames, serialized items, or certain restricted-state orders may require an FFL transfer.

If an FFL is required for your order, our team will contact you with the next steps.
