So should i just save my spare bolt and use it when i get a new barrel?
It looks to be some hair line cracks in my current bolt lug close to the extractor due to a jam i had a while ago. the lug smashed on a rock completely turning it to dust (the rock) and i am probobly being paranoid but i think there are some hairline cracks on the lug now. The current barrel i have now is the stock sig one with only about 700 to 800 rounds on it. So using the bcm bolt would be no good? Should i change the bolt when i change the barrel. I was gonna check headspace on my new bolt and if it checked out, use it and save the sig as a spare. but i dont want excellerated wear on the semi used 800 round barrel i have.
