    What is a Wylde chamber?

    A Wylde chamber is a hybrid mix between .223 and 5.56. For those of you that do not know, the 5.56x45 NATO is NOT exactly the same as a .223 Rem. The 5.56 spec allows for slightly longer chambers for higher pressures. The .223 has a tighter chamber around the neck and is shorter which allows for a bit better accuracy. You can shoot .223 ammo in a 5.56 chamber, but it is DANGEROUS to shoot 5.56 (surplus for instance) ammo in a .223 SPECIFIC chamber. BE CAREFUL. What the Wylde chamber does is allow for 5.56 ammo with slightly tighter chamber for better accuracy. So you can shoot both 5.56 and 223 safely with better accuracy than a standard 5.56 barrel chamber. Now, I may have gotten a little bit of the chamber details a bit off, but one can search the internet and read about it in detail if you would like. It is sufficient to say that you can shoot .223 and 5.56 ammo out of the Wylde chamber without problem and it's more accurate than a NATO 5.56 chamber.
