Modifying for sporting use
Modifying for sporting use can involve the addition of a commercial,
variable power telescopic sight, the shortening of the fore-end, and
(in some cases) the fitting of a new stock. Sporterised rifles may be
re-finished or otherwise customized to the tastes or requirements of
the individual owner- for example, shortening the barrel or
rechambering the firearm in a different caliber. Integrated bayonets,
if present, are removed, as are muzzle devices sometimes for legal
Large numbers of military surplus rifles were sporterised in the 1950s
and 1960s- especially Lee–Enfield, M1903 Springfield, and Mauser K98
rifles, which were in abundant supply after WWII, and therefore
cheaper to acquire than a newly manufactured commercial hunting rifle.
SMLE Mk III rifles, in particular, were popular for sporterisation in
Australia, New Zealand, and South Africa, with many being converted to
wildcat calibers such as
.303/25 owing to both the difficulties of
importing foreign-made rifles (due largely to economic factors), and
also restrictions in the state of

Semiautomatic and civilian versions of assault rifles are marketed as Sporter or S models. The term "sporterising" is also used by some gun control advocates to describe the practice by gun manufacturers of producing civilian models of military-style weapons by removing legally restricted features. For example, a manufacturer might have replaced a pistol grip with a thumb-hole stock, or a flash suppressor with a muzzle brake,in order to comply with legislation such as the 1994-2004 US Federal Assault Weapons Ban. Similarly the design of a rifle may be altered in order to prevent it being fired in automatic or burst mode in order to comply with a region's statutes, with some models having entirely different receivers that prevent the fitting of military select-fire trigger groups. Many manufacturers simply settle for semi automatic-only trigger groups without undergoing extensive modification, and select-fire trigger groups are what is often considered to be the actual machine gun part and are thus heavily restricted. Some gun-control advocates consider these civilian models an attempt to circumvent the intent of the laws. See also
