The MTW Billet Series is our most popular MTW, equipped with our award-winning Inferno GEN 2 engine. New in 2021, the Billet Series has been updated to include a fully-billet lower with integrated trigger guard, flared magwell, steel selector switch, improved electronics with an optical selector sensor, and our advanced feed tube assembly previously only available on the Milspec and Forged Series.


These can only be shipped domestically to the United States. If you are outside of the United States and place an order, it will be canceled. To order an MTW internationally, see our dealer list or contact and we can help you find one. 


The MTW is a high-demand product and has a 2-3 month lead time. We will be shipping them in the order they were placed. All items ordered will be held to ship with the MTW. If you would like other items to ship sooner, please place separate orders or contact to make shipping arrangements.


Please note: Your MTW will come standard with a GEN 2 Inferno and whichever barrel/rail combination you choose in the "MTW length (included)" section. The barrels and rails that you see in the next section are additional options for you to choose. Those modules are in addition to your MTW and will not come pre-installed. However, we have useful videos to show exactly how to install them yourself with ease.

Your MTW will come as either the CQB, SBR, or Carbine version. You may purchase additional rails and barrels to modify.
