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 was 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 sporterized military rifle has been marked "US Property" and includes military sights. Its wood and metal are in fair condition and its bore is in good condition.
