300 m standard rifle is one of the ISSF shooting events.

This event is based in competitions with army-style rifles, and in this form dates back at least to the 19th century, although the early championships had a true army rifle event, using the model of the host country's choice.

[1] 300 metre standard rifle is also on the program of the CISM military world championships.

[2] The rifle must satisfy dimensional, weight, and other requirements stipulated in the rulebook.

The same rifle must be used in all positions without any changes except adjustment of the butt plate, handstop or rear sight.
