Have you a developed a taste for the M4 Forged Receiver from RA-Tech? If you do, here's more good news, they just announced that they are providing custom marking of your own choosing on the receiver. The quote will be dependent on the design and you will need to purchase at least 10 units too. Just make the design yourself and they'll take care of the rest.

You can email the design as JPEG or vector graphics to [email protected].
