Before you attempt to use or shoot your new USR rifle, learn and understand the following basic rules. Your safety and the safety of others depends upon safe and careful handling of your new rifle. Any firearm must be considered a potentially dangerous object requiring particular caution in storage, handling and use. Make sure to always handle and treat every rifle as if it were loaded. NEVER place your finger on the trigger unless you want to fire a shot.

ALWAYS keep the muzzle of your rifle pointed in a safe direction. NEVER point any firearm at anything you do not intend to shoot. Stay alert and be aware of all persons and property within shooting range. NEVER give a loaded firearm to another person.
The mechanical safety's function is to block sear engagement to prevent accidental discharge of the firearm. However, should this device fail, it is possible to fire a rifle even when the safety is in the non-firing position. NEVER place your finger on the trigger when you do not intend to shoot. NEVER place your finger on the trigger or test any safety device when the muzzle of a rifle is pointed in an unsafe direction. NEVER transport a loaded rifle.

STEYR MANNLlCHER AG & Co KG specifically disclaims any responsibility for damage or injury whatsoever occurring in connection with, or as a result of, the use of faulty, or non-standard, or "remanufactured" or handloaded (reloaded) ammunition.
If the round does not fire, open the breech of the rifle and remove the cartridge. If the primer of the cartridge is indented, discard the cartridge in a safe manner. If the primer of the cartridge is not indented, or is lightly indented, or offcenter, have the rifle examined by a competent gunsmith before the rifle is fired again. USE caution to avoid dropping a loaded gun. Dropping the rifle may cause an accidental discharge even if the safety is in the on-safe position.

If you teach your children to shoot, teach them or get them trained by a qualified instructor to treat and use firearms properly, and always supervise them closely. NEVER abuse your rifle by using it for any purpose other than shooting. NEVER fire your firearm near an animal unless it is trained to accept the noise. An animal's startled reaction could injure it or cause an accident.
