Shooting competitions for factory and service firearms

Shooting competitions for factory and service firearms refer to a set of shooting disciplines, usually called service rifle, service pistol, production, factory, or stock; where the types of permitted firearms are subject to type approval with few aftermarket modifications permitted. The terms often refer to the restrictions on permitted equipment and modifications rather than the type of match format.
