Frequently Asked Questions

How Do I Place An Order?

Under our products page you can select a product or service and securely place your order using a credit or debit card.  Whether you are purchasing a ready to ship item or sending in your firearm for us to modify, the process is the same. You will be prompted to select the various options or upgrades that apply. If you don’t see an option, or have a special request, you can leave it in the notes section at the bottom of the product page. 

Shipping Instructions:

All firearms (lower receivers, frames, etc) must be shipped via UPS or FEDEX. Check your local and state laws to ensure compliance. USPS flat rate boxes are the best for slides and other non-regulated items. Since we are an FFL, you can direct ship to us, and we can ship directly back to you without the need of going through another FFL. If you would like to use a local gun store or FFL, that’s no problem, just include their name and address in the notes and have them send a copy of their FFL to


In the box, please include a copy of your order form.

For frames and complete firearms also include a copy of a valid drivers license, carry permit, or military ID.
