{{Main|Swing rifle}}
The Swing was developed in 1970 in the United Kingdom as a purpose-built target rifle for use in [[National Rifle Association (United Kingdom)|NRA]] competition. [[Fullbore target rifle]] competitions historically used accurised examples of the prevailing service rifle, but it was felt these had reached the end of their development potential.

The Swing bolt featured four lugs on the bolt head, at 45 degrees when closed - splitting the difference between the vertically locking Mauser and horizontally locking Enfield bolt designs. Supplied with [[Schultz & Larsen]] barrels and a trigger derived from the Finnish Mantari, the Swing was commercially successful, with the basic design reused in the Paramount, RPA Quadlock and Millenium rifles.<ref>{{cite journal |author1=Laurie Ingram |title=The SWING SIN71 Rifle Prototype |journal=NRA Journal |date=2002 |volume=LXXXI |issue=Summer 2002 |page=24 |url=https://nra.org.uk/wp-content/uploads/2017/04/2002summer.pdf |access-date=1 September 2022 |publisher=[[National Rifle Association (United Kingdom)|National Rifle Association]] |language=English}}</ref>
