Vektor CR-21

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