The potential dangers of utilizing .556 NATO in a .223 Remington barrel embody:
- Extreme Strain: This could trigger the brass casing to rupture, resulting in a doubtlessly catastrophic failure of the firearm.
- Bulging of the Chamber: The chamber partitions could develop past their design limits.
- Harm to the Barrel: The barrel can bulge, crack, or burst.
- Danger of Harm: The shooter and anybody close by are at a excessive danger of damage from escaping fuel or particles.
