Due to the recent increase in order volume, the shipping of some items may experience significant delays. Items shipped from our own warehouse can be shipped much sooner than items shipped direct to you from one of our fulfillment suppliers. Additionally, our supplier network has currently prohibited the canceling or updating of all orders after they have been placed. We appreciate your patience during this time.

  • the difference in .223 and 5.56 is the thickness of the brass and pressure. You can shoot .223 in a 5.56 barrel with no problem. I would not shoot 5.56 in a .223 barrel unless it is a .223 Wylie barrel.

  • Vincent, This is correct. This rifle has a barrel that is stamped 5.56NATO so it will handle the 5.56 and lower pressure .223 round no issue.
