IMPORTANT NOTE: This file may be mirrored for individuals who utilize a buffer tube that folds to the left, such as the product sold by Law tactical and and other similar products.REV.3 of my pack block for AR pattern uppers and lowers that allows you to transport them as a clean, compact, and retained package.  Upper and lower are now parallel to allow clearance for those running an AFG.Provisions have been made to protect your FCG, retain and protect your BCG, and prevent ingress of FOD into components including installed magazine during transport. I would recommend users utilize Avibank quick release pins or similar. Avibank P/n BLC4RA09S.I've added an additional file that doesn't contain my makers mark branded into the bottom as it can cause adhesion issues with the first layer on uncalibrated or unleveled printers. If you do use the branded just set the first layer down slow and after that you can run normal printing speed.
