From Ruger’s website:

Ruger has issued a Product Safety Bulletin for certain Ruger Precision Rifles due to the potential for interference between the aluminum bolt shroud and the cocking piece (also known as the firing pin back). Although only a small percentage of rifles appear to be affected and we are not aware of any injuries, Ruger is firmly committed to safety and is offering replacement aluminum bolt shrouds for affected rifles in order to eliminate the possibility of such interference.

THIS SAFETY BULLETIN DOES NOT APPLY TO RUGER PRECISION RIFLES WITH POLYMER BOLT SHROUDS.

Ruger Precision Rifles (regardless of caliber) that have an aluminum bolt shroud and fall within the following serial number ranges are potentially affected: 1800-26274 to 1800-78345 or 1801-00506 to 1801-30461.
