In my experiences with them, they tend not to be very accurate and they tend to lead up the barrel. (You are running a slightly smaller, all lead bullet that will obturate up to full diameter for the barrel).
5.56 / .223 barrels have a much faster twist rate than barrels meant for .22LR. (Typical twist rate for .22LR is 1:16", whereas 5.56 is 1:7, 1:8, 1:9 ie)
I have also had lots of issues with function; feeding, extracting, etc.
I built my wife and stepson both dedicated .22LR ARs using Nordic Components complete uppers. (My wife's is a 9.5" pistol and my stepsons is a 16" "sniper rifle").
Both of them run fine and shoot great.

Hers is currently a dark plum colour and does not have the arm brace on it.
We are still waiting for stepson to decide what colour he wants his.
