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).
Ruger says that only a small percentage of rifles appear to be affected, and that the company is not aware of any injuries. That said, the company is committed to offering replacement aluminum bolt shrouds for affected rifles in order to eliminate the possibility of such interference.
Per Ruger: "Some Ruger Precision Rifles may experience interference between the aluminum bolt shroud and the cocking piece (also known as the firing pin back). In rare instances, the interference can disrupt the firing mechanism and cause it to not function properly. Possible results of this interference are light primer strikes or, in extreme cases, the rifle may not fire when the trigger is pulled. If the rifle fails to fire when the trigger is pulled, it may fire when the bolt handle is subsequently lifted. In rifles where this condition exists, it often resolves itself as the parts wear and the interference is reduced."
Potentially affected serial numbers include: 1800-26274 to 1800-78345 or 1801-00506 to 1801-30461.
The company's official statement says that though all rifles in those batches are potentially affected, most rifles will never experience the issue. However, if you have experienced light primer indents or failure to fire while shooting or dry firing your Precision Rifle, you should obtain a replacement bolt shroud, which Ruger will provide free of charge. If you believe your rifle is affected or are unsure if your rifle is affected, you can request a free replacement bolt shroud by filling out the appropriate form on the Ruger website.
