We accept Visa, Mastercard, checks, and money orders. A 50% deposit will secure your spot on the production run, or contact us to arrange a payment plan.

Paying by cash, check or money order; please call for cash discount.

We produce our uppers and lowers in batches we call "production runs". Each production run takes about 6 months to complete. At the time of order we will inform you of our schedule and when we estimate the production run to be completed. Due to delays out of our control such as material supply and work done outside of our shop (heat treat, barrels, etc) we do not promise when a run will be completed and your order delivered. However, we do all that we can to follow our own schedule. The bottom line is that we will deliver a superior product, even if delayed, before we will cut corners on quality.

Florida residents please add the appropriate sales tax for your county.

No FFL required for uppers. Lowers and complete rifles must ship to a FFL. All BATFE rules apply.
