I'd checked all four of my bolts, which came from various sources. In no particular order.

In all cases, firing pins are completely interchangeable (right?) and bolts head space identically between all rifles (again, right?)

When at the range or in the field, a second rifle is always the perfect backup. Plus, there is tremendous peace of mind when cleaning BCG's with no need to concern myself about accidental mixups.
