Also known as The ''Jungle Carbine'', The British Mark I, No. 4 Rile was manufactured by Lee-Enfield Firearms Company. 300,000 such Rifles were produced between 1944 and 1945. Although a wood and metal component weapon, rubberized outer portions, designed to make the weapon fare well in tropical environments, would earn it the unofficial nickname of ''Jungle Carbine''. The weapon – while used in The Pacific Theater (1944), variants were used in Europe as well. Weighing 8-pounds, The No.4 Rifle was 40-inches in length and fired the .303 round. The weapon was bolt action and clip fed, with a trained Marksman capable of firing 20 to 30 rounds per minute. It's minimum range was 500 yards, with the ability to range as far as 800-yards. By virtue, it's lightness and clean action did make it an effective ''Jungle Warfare'' weapon. Other innovations was a larger flash suppression system with helped in decreasing it's report signature. Variants also featured a bayonet attachment. The common reported issue with The No. 4 was that once ''battle sight zero'', or adjusted targeting of the rear (windage) sight was set, the vibration from repeated firing caused it to jump or ''wander''. This caused problems in aiming. While no exporting to Foreign Nations was seen in any great bulk, versions of The No. 4 would make their way into The American civilian market – as a Sporting Gun. Similar variants were experimented with by The British Army, as ''Tanker'' Crew weapons.
