I've got a DPMS SS bull barrel upper, and the guys at DPMS recommended that for reliability reasons, I should stay with .223 because of the tighter tolerance. It is chambered for 5.56 however, as all (?) DPMS uppers are.

You guys have any problems with 5.56 in your bull barrels?

No My bull barrel is not Stainless though.

So far, put 60 rounds each of PMP's .223 Remington and Winchester Q3131 5.56 x 45mm through my Colt's 20-inch bull barrel. No problems so far. [:)] Edited to add: Oh yeah, no stainless barrel here either.

I have a 20" DPMS with the SST bull...I ONLY shoot XM193...and with excellent results. The .223 vs 5.56 controversy is mostly bullshit.

Nice. Federal XM193 is on sale at the local sporting goods store... perfect timing.

I have to agree with this. I would pay money for the evidence of a commercial .223 chambered Ar-15 that went kaboom on 5.56 military ammo. The pressure issues come into play if you reload and are using heavier match rounds and start pushing the pressures.
