Go into Magpul's industry page on here and say you want the ACR stock back. I have a thread about it that's probably archived by now; I also post it on every wishlist for the year. They claim the molds wore out, I don't think so because there would be way more in circulation if that were the case. How many CTR stocks are out there? Unless they just replace those molds? An ACR stock with minimal redesign for 1913 rail interface as the packaged option and quick swap hinge feature to other platforms would be a huge market.
