AR Pack Block REV.2
prusaprinters
Pack block for AR pattern uppers and lowers that allows you to transport them as a clean, compact, and retained package. 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.EDIT: added small counterbore to FWD and AFT holes where upper mounts for users who would like to utilize Avibank quick release pins. Avibank P/n BLC4RA09S is what I utilize.
