Worked example

842 current recorded rounds − 500 at the recorded service baseline = 342 rounds since service.

How the calculation works

Use whole-round counts from the same firearm. The baseline cannot exceed the current recorded total. A corrected earlier baseline can change the result without any new activity occurring.

What the result does not establish

This count does not assess condition, safety, or a maintenance requirement. Consult the applicable source for actual service guidance.
