Browning 1919-A4 Machine Guns

 

The Belt-fed Browning 1919 A-4 was the U.S. Militarys light machine gun for decades and it can still be found in use around the world. Master Armorer, John Bush, will teach you how this gun works step-by-step, along with complete disassembly, reassembly, troubleshooting, and repairs. You will also see many rare accessories, tools, belt-loading machines, and a number of different caliber conversions including 8mm & .308. We also take you on a trip to the range where you will see how to properly set up the gun on a tripod, and field adjust headspace, as well as close-up views of several different guns firing cloth and link belts. This exhaustive course is over 3 hours in length and covers everything in detail.

If you want the quick course on how to get the Browning 1919-A4 Machine Guns 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.)

Among the items covered are:

History

 

  • The history of the Colt manufacturing relationship with John M. Browning, the inventor of the 1919 Machine Gun, is explored
  • After many design changes to the Browning machine gun, in 1917 the United States Military tested the machine gun that now utilized downward ejection. After 20,000 rounds were continuously fired through the weapon with no failures, there was some skepticism, as they thought this was some type of fluke. Therefore, Browning took out another machine gun and fired continuously for around 48 minutes with no failures and the Ordinance Department was silenced. They knew that they had an extraordinary firearm in front of them
  • During WWI, Colt was busy manufacturing other firearms, including another one of John Brownings designs, the Potato Digger (M1895 Machine Gun.) Thus, many of the 1917 machine guns were manufactured by New England Westinghouse, and Remington. By the end of WWI, 56,608 model 1917s were manufactured for the Military
  • We are shown a variety of tech manuals and other literature for the Browning machine guns
  • After even more design changes were made, the model 1919-A4 was put into production and many other countries adopted this .30 caliber weapon besides the U. S.
