This is the order link for a custom serial number for your 416 lower receiver. You can now match your factory upper serial if you choose.

• The lower will be engraved with the serial number you enter at checkout
• The lower will then be sent to anodizing (black or RAL) and selector markings color filled on return
• The lower will then be shipped to either your FFL or Drunk Irish Customs for factory markings as you have selected

*NOTE: Buy purchasing this, please understand that your lower will not ship immediately. It will be batched with the outgoing receivers which may take 4-6 weeks to ship to your FFL.

If your serial number has been used by a previous GRW customer, it will no longer be available
