converting an Ar1522 to a .223
Hi.
I'm sure this has been covered before, but I'm new to the forum and tried digging through the threads with no luck.
Someone mentioned to me that a S&W AR 1522 can be converted to a .223 by attaching a .223 upper to the AR 1522 lower portion.
Is there any validity to this? is is that simple?
Thanks
