Just got a new upper that just says 223 on the barrel, does this mean that it will only shoot 223 and not 5.56 nato, what is the difference between the just 223 barrels and the ones that say 223/5.56 nato? Thanks

Who manufactured the barrel ? It is almost certain if it is stamped .223, that is all you should attempt to shoot through it.

5.56 runs higher pressures than 223.

It is a DPMS 20" 1/8 twist.

223 rem or 223 wylde or just 223?

The barrel just says 223, I assume rem.

I'm not a DPMS expert, but it sounds like you have a .223 chambered barrel. I would not shoot 5.56 through it. Although I've yet to see a single case where shooting 5.56 in a .223 barrel ended badly.

YMMV

I don't mean to hijack this thread, but my question is along the same idea. I also have a DPMS. Where on the barrel would this be stamped? On my lower, there is a 5.56/.223 stamp. Since I bought the rifle as a whole, I assume this means the barrel is as well, but where would I look on the barrel itself?

Thanks.

Ok thanks for the help.

Look for a stamping on the barrel, forward of the front sight base.

Irgrunt, based on the 1/8 info, is it a stainless steel barrel?
