I'm waiting on some stamps, as soon as they come in I'll be replacing an HBAR upper with a new short .300BLK upper. I intend to reuse the same bolt and carrier in the new upper. The bolt has maybe 2000 rounds on it, tops. Likely less. Bolt was sold as being MPI and all that good stuff.
Searching seems to indicate that I am probably OK to reuse the bolt. Checking headspace would be a good idea but not strictly necessary.
Am I doing anything needlessly foolish or dangerous?
