I do know that an acr adapter for the m11 is in the works. I have the 3d printed version I checked out on my m11. Final tweeks are being made and a final version will be produced. Not sure on the timeframe on that though. Also I believe more m10 acr adapters could be coming I'll have to ask Jordan about it.
Thank you Sir, my pending M10/9 would love it! So I Don't Miss Out, reckon to best check often: Norse Forge, here, and Norse Forge @ FB.
