Sounds about right, I underestimated the number of rifles that were originally 223 Wylde.
This ^^
I had issues and sent mine back. Overpressure and blown primers using factory 5.56 ammo with the original 223 Wylde chamber.
I'm not sure if they just re-reamed with the 'good' 223 Wylde reamer they had or if it was redone to 5.56.
Whatever they did on mine factory 5.56 runs no issue now, but my barrel is still stamped .223 WYLDE - obviously worth more as a collector if I ever sell it, rotflmao
