These are run in minimum batches of 20 units. It may take a few weeks for us to have enough bolts to begin this custom machining process. Turn around time may exceed 8 weeks. However, we will make every effort to get your bolt finished in a timely manner. If we do not reach the minimum batch size within a given 8 week period, we will begin machine work on the orders we have in queue, regardless of the quantity.
This is a service to convert the bolt from your Sterling MK4 parts kit for semi auto, closed bolt operation.
How it works:
- Add the product to your cart and complete the checkout process.
- Pack up your bolt and ship it to us, addressed to: Freedom Machine Works LLC. PO Box 112 Diamond, OH 44412. We strongly recommend using a small flat rate box, insured for the full value.
- Send us an email to confirm that your bolt is on the way.
- We machine your bolt for all of the necessary modifications and ship it back to you ready to run.
A new striker and spring set are included in the price of this service.
Return shipping is also included at no additional charge.
