The failure (1) can be corrected by an operator but requires more than 10 minutes (2) cannot be corrected by an operator and requires assistance (no time limit) or (3) requires higher level of maintenance or correction by an authorized operator cannot be accomplished because of unavailability of necessary tools, equipment, or parts. Class III failure: A failure of a severe nature.Only the equipment and tools issued with the weapon may be used to correct the failure. The last of the M27s come into the Marine Corps inventory this year and are expected to be in the hands of each infantryman from platoon commander and below by mid-2021, officials said.
Class II failure: A failure that may be corrected by the operator, and that requires more than 10 seconds but not more than 10 minutes to correct (less the TM/OM defined cool down period if a hot barrel condition exists).Class I failure: A failure that may be immediately corrected by the operator within 10 seconds or less while following prescribed immediate action procedures.The MRBF for Class III failures shall be 15,000 (Threshold), 20,000 (Objective). The UUT shall have a Mean Rounds Between Failure (MRBF) of 900 for Class I and II failure combined (Threshold), 5,000 (Objective). Three Units Under Test (UUTs) were provided for each model under evaluation.ī. Reliability/Endurance Testing Mean Rounds Between Failure (MRBF)Ī. The Unit Under Test (UUT) shall have a Mean Rounds Between Failure (MRBF) of 900 for Class I and II failures combined (Threshold), 5,000 MRBF (Objective). This is the Round One definition of failures by class: Reliability Testing (If you have only a few failures, but they’re take-the-gun-to-the-bench failures, that’s a whole other thing than a higher quantity of simple failures that are rectified in seconds by operator immediate action (a la SPORTS drill on the M16/M4 series). This is presumably due to the distribution of the failures. Note that some of the rejected proposals (C, E, F) had fewer failures than the ones that proceeded.

Kind of a raw break for that unfortunate competitor, Code Letter I. The 10 th IAR Bid Sample, Competitor I, was determined unsafe for live fire due to a lack of proof marking.
