WARNING: This is a BETA model of my M4 to AK Magazine adapter. I can't guarantee that the tolerances will fit your AEG, or that it'll work. If you purchase it, you do so at your own risk - If you do buy it, please report back what tolerances did not fit, and I can fix them. This model is part of an ongoing project to utilize airsoft M4 and M16 magazines in AK model AEGs (Automatic Electric Guns). I originally created this model in 2012 as a part of an engineering graphics course, as a test for my alma mater's 3d printer. This is the second iteration of the print, which includes a magazine release printed together with the magazine adapter, on a living hinge. You can see the design progress on my website. http://www.cardella.tk/2012/12/ak-stanag-mag-converter.html
