Enfield Rifles


The Lee-Enfieldbolt-action, magazine-fed, repeating rifle was the main firearm used by the military forces of the British Empire/Commonwealth during the first half of the 20th century. It is felt by many experts to be the best battlefield bolt-action rifle ever issued. In its L-42 sniper version, it remained in service until 1993. It is still in service in some of the commonwealth countries. International armaments expert, John Bush, gives you the complete instructions for disassembly to the last screws and pins, inspection, cleaning, and reassembly that will make you an expert on the care of these guns.

This course is designed to help all of you owners who love the gun to understand clearly, how to identify all the Enfield variations and many rare accessories are shown. It also covers repairs and sporterizing. In true AGI fashion, we use a factory cut-a way gun that allows you to actually see how the various (normally hidden) parts work and interact. If you want the quick course on how to get this timeless, classic, bolt action rifle apart, back together, and operating as intended, then this course is for you (if you want the long course, look into our basic 108 hour Professional Gunsmith Course.)
