What is the tolerance level when conducting the end-for-end test?

The tolerance level for conducting the end-for-end test is set at +/- 0.4 mils. This level of tolerance is established to ensure the accuracy and precision of the Howitzer's aiming procedures. In artillery operations, even slight deviations can lead to significant errors in targeting, which underscores the need for maintaining a specific tolerance level during testing processes.

A tolerance of +/- 0.4 mils allows for some margin of error while still ensuring that the performance of the artillery piece remains reliable and effective. This level of precision helps in maintaining the operational integrity of the M777A2 Howitzer, making it suitable for various firing scenarios and ensuring that it meets its required specifications.
