If my lower says "multi caliber" do I have to engrave the caliber I'm building it into in order to make it a SBR? Also where is a good place to get it engraved around Marietta? Thanks

When you fill out the form 1, you must designate a caliber. Yes caliber must be engraved but once you have an approved form 1, you can use other uppers if you still have possession of original configuration.
