Safety Alert

Smith & Wesson M&P 15 Rifle


This applies to all M&P15-22 firearms manufactured before February 1, 2019.

As indicated on their Safety Alert …
“Smith & Wesson 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.

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.”

They have outlined an inspection procedure to ensure that all products in the field are safe to use.

Faulty bolt may cause discharges without depressing the trigger.

  • You may inspect the bolt yourself according to their procedure.
  • Send the bolt to Smith & Wesson for inspection and replacement if needed.
  • Bring your M&P15-22 to Burnt Knoll Firearms for inspection with the Smith & Wesson gauge and replacment if necessary.
