The Lee-Enfield bolt-action, magazine-fed, repeating rifle was the main firearm used by the military forces of the British Empire and Commonwealth during the first half of the 20th century. The No. 4 action is similar to the previous Enfields, but lighter, stronger, and easier to mass produce. The No. 4 rifle is considerably heavier than the No. 1 Mk. III Enfield, largely due to its heavier barrel. Unlike the earlier SMLE, the No 4 Lee-Enfield barrel protrudes from the end of the forestock. The Mk 1 variation of the No. 4 is differentiated by a simpler notch on the bolt track of the rifle's receiver. This rifle was made in the US by Savage Arms and features a fixed post front sight with a folding peep rear sight, a 2-position safety, and a 10-round magazine. Its wood, metal, and bore are all in very good condition.
