Smith & Wesson has issued a Safety Alert for the M&P 15-22 Rifle and Pistol.
Some out-of-specification bolts have been discovered that have the potential to cause an unintended discharge when the bolt moves forward, under spring tension, into battery with a loaded magazine inserted.
Smith & Wesson believes these discovered bolts to be isolated incidents, but takes the potential for an unintended discharge with any if their firearms seriously.
If you own a Smith & Wesson M&P 15-22 Pistol or Rifle manufactured before February 1, 2019, cease shooting it immediately until the bolt can be inspected, and if necessary replaced, at no cost, by Smith & Wesson. The company has developed an inspection procedure that can be done by the customer, or a qualified gunsmith. Or the customer can ship the bolt directly to Smith &Wesson for inspection.

I have the Smith & Wesson gauge and inspection procedure. Since firearm safety is the primary reason I do what I do, I am more than happy to perform this inspection at no cost.
