.303 Cal No 4 Rifle

Due primarily to its simplicity of operational characteristics as well as ease of maintenance and repair, the Rifle, .303 Calibre, Lee Enfield, No 4, All Marks, is used in limited numbers, as a personal defence weapon, by members of the following groups:

  1. Canadian Rangers;
  2. Search and Rescue; and
  3. Mapping and Charting.

The Rifle, .303 Calibre, Lee Enfield, No 4, All Marks, is a heavy barrel, manually operated bolt action, magazine fed rifle, capable of firing single shots only. It fires rimmed cartridges from a detachable ten round magazine.

The No 4 series rifles were developed from the British forerunner, the Short Magazine, Lee Enfield Mark VI (SMLE). The Rifle, .303 calibre, Lee Enfield, No 4 Mk 1 appeared in 1931 as a refined production version of the No 1 rifle adapted from the SMLE. The Rifle, .303 calibre, No 4 Mk 1 was further redesigned for mass production as the Rifle, .303 calibre, Lee Enfield, No 4 Mk 1 * in 1939. This version of the rifle became standard issue for the British Commonwealth during World War II.
