Smith & Wesson Corp. announced today that the Company has identified two M&P15-22 firearms from recent production on which the breech face counter bore depth was not within manufacturing specification. In those firearms, the lack of depth may allow the bolt, upon closing, to crush the rim of the case, causing the round to fire, cycling the bolt, and potentially resulting in multiple discharges without depressing the trigger.

This issue can occur in the following two scenarios:

• 1) With a loaded magazine in the firearm and the bolt locked to the rear, depressing the bolt release to allow the bolt to drop freely may ignite the round as the bolt closes without engaging the trigger and with the safety selector in either the safe or the fire position, and may also result in multiple discharges.
• 2) With a loaded magazine in the firearm, bolt in the closed position and a round in the chamber and the safety selector in the fire position, depressing the trigger will cause the round to fire normally, however as the bolt cycles, the next round may be ignited by the bolt crushing the rim of the case as it closes, causing multiple discharges.

This Safety Alert applies to all M&P15-22 firearms manufactured before February 1, 2019. We believe these are isolated incidents, however, any unintended discharge of a firearm has the potential to cause injury. Therefore, out of an abundance of caution, we are asking all consumers of all M&P15-22 firearms manufactured before February 1, 2019 to immediately inspect their firearms for this condition.
