is the DPMS 20" A3 classic rifle chambered in 556 or .223? I looked on their website but couldnt find the a3 classic. If something is chambered in .223 it cant shoot 5.56 right?

.223 chamber is not safe to shoot 5.56 in.
5.56 is safe for .223.

Call DPMS, thats going to be your best answer but im almost positive thats its 5.56.

5.56 is what they claim but I have seen a number of mis-reamed chambers.
