Sporterising, sporterisation or sporterization is the practice of modifying military-type firearms either to make them suitable for civilian sporting use or to make them legal under the law.


Modifying for sporting use

Modifying for sporting use can involve the addition of a commercial, variable power

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 reasons. Large numbers of military surplus rifles were sporterised in the 1950s and 1960s- especially

militaries. Even in states and countries where there were no such restrictions, many sporting shooters at the time found it expedient to cut down their ex-military SMLEs, in the interests of reducing weight or improving handling. The practice of sporterising is frowned upon by most collectors and firearms enthusiasts because many military surplus rifles are highly collectible in original condition. Permanently altered sporterised firearms often sell for less money than military firearms in original condition. A number of "Commercial" sporting conversions of military surplus arms were undertaken in the 1950s by Interarms, Golden State Arms, the Gibbs Rifle Co. and Navy Arms in the United States. These rifles are often considered to be collectible in their own right, and are not generally regarded as being "sporterised" in the usual sense of the word.


Modifying for compliance with legislation

Semiautomatic and civilian versions of assault rifles are marketed as ''Sporter'' or ''S'' models. The term "sporterising" is also used by some 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 On a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to the how one would hold a conventional pist ...

. 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.
