It is normal for a new production bolt to require minor fitting to one of the lugs before it will lock into battery depending on the fit of the other parts. When Kalashnikov pattern firearms are built the bolt lug is typically hand fitted to each firearm during assembly at the factory. WBP has removed a small amount from the necessary bolt lug so it will work with most rifles without adjustment. However, it is still possible you will need to do some additional fitment
