How often should you replace: - Gas Rings - Bolt - Extractor Spring / Insert - Bolt Carrier / Gas Key - Barrel Are the guidelines different for auto vs semiauto? |
You could purchase headspace gauges and check your head spacing once a year. But I think the average recreational shooter will never wear out a bolt.
When you start to experience FTE’s.
Bolt carrier- Probably never. If you perform the gas ring check, and your gas rings fail. You replace them with a new set and it still fails the test, then chances are your carrier is worn past the limit. But again, you carrier should last you a life time. Carrier key- If you experience short cycling and discover your gas tube is leaking do to wear, you might want to also check and possibly replace your carrier key.
The barrel might warrant replacement along with the bolt when head spacing fails, or when your groups open up and are no longer acceptable to you.
With full-auto verses semi-auto you might want to increase the frequency of your inspections. |
