The Vektor CR-21 ("CR-21" being an abbreviation of Combat Rifle 21st Century) is a prototype South African assault rifle chambered for the 5.56×45mm NATO cartridge. It was designed by Denel Land Systems as a possible replacement for the South African National Defence Force's current service rifle, the R4 assault rifle. However, Denel has since shifted focus to offering an upgraded version of the R4 to the SANDF instead.
