The L59A1 was a conversion of the No. 4 rifle (all marks) to a [[drill purpose rifle]] that was incapable of being restored to a firing configuration. It was introduced in service in the 1970s. A conversion specification of No. 1 rifles to L59A2 drill purpose was also prepared but was abandoned due to the greater difficulty of machining involved and the negligible numbers still in the hands of cadet units.

The L59A1 arose from British government concerns over the vulnerability of the Army Cadet Force and school [[Combined Cadet Force]]s' (CCF) stocks of small arms to theft by terrorists, in particular the [[Irish Republican Army]] following raids on CCF armouries in the 1950s and 1960s. Previous conversions to drill purpose (DP) of otherwise serviceable rifles were<ref>{{cite web |last1=HARC |title=Reference Site |url=http://Www.rifleman.org.uk/L59A2_Drill_Purpose_Rifle.html |website=Www.rifleman.org.uk |publisher=Rifleman.org.uk}}</ref> not considered to be sufficiently incapable of restoration to fireable state and were a potential source of reconversion spares.

L59A1 drill rifles were rendered incapable of being fired, and of being restored to a fireable form, by extensive modifications that included the welding of the barrel to the receiver, modifications to the receiver that removed the supporting structures for the bolt's locking lugs and blocking the installation of an unaltered bolt, the removal of the striker's tip, the blocking of the striker's hole in the bolt head and the removal of most of the bolt body's locking lugs. Most bolts were copper plated for identification. A plug was welded in place forward of the chamber, and a window was cut in the side of the barrel. The stock and fore end were marked with broad white painted bands (often with red bands, and also rarely seen blue bands or stripes) and the letters ''DP'' for easy identification.
