I would like to make a suggestion. What you have done is very good the end product is most definitely top notch and appears very well made, However;
Due to the difference in finished product, it may be prudent to bead blast the product to produce a more linear texture with the rest of the gun, your thoughts? Or are my eyes just being deceived?
Second, leave off the made in USA part. There are ZERO requirements that this be needed. You are in the U.S. right? Provide a receipt and that will suffice.
