High-powered air rifles are generally classified as non-restricted firearms. However, the classification depends on the exact design of the air gun. Air rifles manufactured to resemble an assault rifle could be non-restricted, restricted or prohibited depending on the exact model imitated. High-powered air rifles would also be prohibited firearms if fully automatic or if they have a sawed-off barrel. They could also be restricted firearms if they have a folding stock that reduces the overall length to less than 660mm.
