Hello, I am looking for someone who can draw a 3D CAD drawing of an AR-15 Polymer style magazine that feeds .223 and 5.56 rounds. YOU MUST own, or have access to a magazine of this type. Google PMAG for information of what type of magazine I am looking for. Google PMAG Rebuild kit to see the parts that will be associated with the CAD Drawing, minus the spring as the spring cannot be made by polymer injection molding. PREFER Someone living in the USA as they would be more likely to be able to get access to this kind of magazine.
