Dedicated .22WMR or .22LR AR Upper ??

[MD_Willington]

Hello THR members...

I spent a little time searching on line for a dedicated .22WMR upper and didn't find anything...

Do any of you know of a company that would happen to make such an AR upper?

I'm also interested in a dedicated .22LR upper, IIRC DPMS or someone makes one, anyone have one, and if so how does it run?


Thank you for your time
