nope ..... 223 Wylde is a chamber that gets the best out of 5.56mm Surplus or Commercial 223 factory ammo in a 1:8 twist barrel.... its a good thang !
I think the Wylde will shoot up to an 80 grain round at higher pressures. Why spend $1450 on an AR to shoot .223 or 5.56 when you can spend a lot less? I don’t get it. Unless you want to load your own or search for hard to find ammo. To each his own.
