The Vektor R4 is the South African standard rifle and is a slightly modified IsraeliGalil; the modifications consisted of changing the butt and fore-end to synthetic materials rather than steel, in consideration of the bush temperatures common in Africa, and lengthening the butt since the average South African is rather larger than the average Israeli. The Vektor R4 is chambered for the 5.56 mm M193 cartridge and has a rate of fire of 700 rounds-per-minute from a curved 35 round box magazine. Research Vektor R4
