Come on Magpul, there's a huge market of buffer toob-less rifles coming to market and many out now that are just begging for ACR stocks. There are some knockoffs and bad attempts out there coughF5cough. A 1913 adapter would be clutch, probably the one it should ship with, and other end plate adapters as another product line.
Or do me a solid and float me an ODGreen one, I'd be much obliged .
