Yeah, Colt's 22LR AR is made by Umarex (sp?).
Like others have already said, if you get a .22 with a regular lower then you can change it out to anything you want. But, Colt's .22 AR, Smith's M&P 15-22, and Sig's .22 AR all use a different lower. I'm not sure what companies make their .22's with standard lowers, I know I've seen one from CMMG, but not too many others. It would probably be easier to buy one in 5.56/.223 and convert it to .22 via a conversion kit or new upper. You wouldn't have much more invested in it that way either.
