Description:
Here we offer both Sten MK2 or MK5 (per customer’s request) full-automatic receiver tubes. These precision-manufactured receivers are designed for building NFA-regulated post-sample machine guns in accordance with military specifications.
Lead Time:
Expect a two-month lead time for these pre-order items. Each receiver tube will be crafted to order, ensuring that you receive the highest quality component for your build.
Important Legal Information:
SOT & Law Letter Required: These items are only available to SOT holders who possess a valid law letter. Please ensure that you have verified both your SOT status and the law letter authorization before making a purchase. These are NFA-regulated items that require both an SOT and law letter for lawful transfer.
Once the receiver tubes are manufactured, they will be tax-exempt transferred to the buyer via ATF Form 3, provided the buyer is a qualified SOT holder and has supplied a valid law letter for government or lawful entity transfer purposes.
Compliance:
Non-compliant purchases will be rejected. The buyer is responsible for ensuring they meet all NFA regulations. Please do not attempt to purchase if you are not an SOT holder or do not have a valid law letter for the transfer.
This is a brand new MP40 full-automatic receiver tube—the essential part for building your own MP40 submachine gun. Manufactured to military specifications with precise attention to detail, this receiver tube is perfect for those looking to build an NFA-regulated post-sample machine gun.
