Can you convert a M&P15 .22 to fire a .223 / 5.56 ?
No. But you can do it the other way around.
What he said ^^^.
You cannot put a 5.56 upper on there for a couple of reasons-
First, the size of the upper/ lower is different between the .22 LR and a regular AR.
Second, the .22 rimfire has no buffer.
