FN America, LLC, announces today the mandatory recall of certain FN M249S® semi-automatic, belt-fed rifles in both standard and PARA configurations. A recently identified design issue within the hammer group of the rifle may adversely affect the rifle’s reliability. Under certain circumstances, a reset failure within the hammer group may cause the M249S to cease to function, causing an unsafe firing event. To correct this condition and restore consistent, proper and safe operation of the firearm, it is necessary to replace the hammer group. FN is instructing customers to discontinue use of these rifles immediately and return affected products to FN directly for installation of a new hammer group, at no cost. Not all FN M249S serial numbers are affected by this recall. Therefore, FN M249S owners are asked to please visit the FN M249S Safety Recall webpage and input their serial number. If the firearm is affected, further instruction on returning the FN M249S for service will be provided. Note: Please do not ship any affected product to FN until a FedEx label has been generated and sent to you. If the firearm is not affected, a message stating such will be displayed. In the interim, FN asks that customers not operate their FN M249S Standard or Para until the hammer group has been replaced. FN is deeply committed to providing customers with the safest, most reliable firearms possible. As such, it is imperative that all recalled product is received in back immediately. Patience and cooperation is appreciated as we receive, inspect and service these firearms. We will make every effort to return the product back to customers within 30 days of receipt.
