3. AR-15 Caliber Conversion Safety

What are the safety risks associated with AR-15 caliber conversions?

AR-15 caliber conversions can be a safe and effective way to change the caliber of your rifle. However, there are some safety risks associated with this process that you should be aware of.

  • Improper installation: If you do not properly install the new caliber parts in your AR-15, it could cause the rifle to malfunction. This could result in a dangerous situation where the rifle could fire without you pulling the trigger.
  • Using incorrect ammunition: It is important to use the correct ammunition for the caliber of your AR-15. Using the wrong ammunition could cause the rifle to malfunction or even damage the rifle.
  • Insufficient headspace: Headspace is the distance between the bolt face and the chamber wall. If the headspace is incorrect, it could cause the rifle to fire out of battery. This could result in a dangerous situation where the rifle could fire without you pulling the trigger.
  • Insufficient barrel twist rate: The barrel twist rate is the rate at which the rifling in the barrel twists. If the barrel twist rate is not correct for the caliber of ammunition you are using, it could cause the bullets to keyhole. This could result in a loss of accuracy and could also damage the barrel.
