There are tons of websites to explain why.
Just don't do it.
Make sure your chamber and barrel are marked 5.56 and there will be no worries.
Please quote the websites that show why not to use 5.56 in a .223 Wylde.
If no-one could/did shoot 5.56 in the .223 Wylde it would make no sense to chamber a precision upper in .223 Wylde right?
Why not chamber in straight .223 to keep the dimensions as tight as possible for maximum precision?
Does anyone here shoot 5.56 from your .223 Wylde?
