Sterling Submachine Guns

The 9mm Sterling sub machinegun is the most reliable SMG in the world. Designed and produced in the United Kingdom, it was torture tested in trials of mud, sand and even frozen in ice. In these tests, the Sterling outperformed the H&K MP-5 and even the robust UZI, making it the king of the SMGs when it comes to reliability. It was used all around the world in various wars and British territories and was discontinued only because of politics and the high cost of manufacture. In addition to being very reliable, it is also extremely controllable and accurate, as you will see as we fire these guns in semi and full auto.

Instructed by Master Armorer John D. Bush, in the course you will learn how to completely disassemble the gun down to its smallest parts, the equally important complete reassembly, along with trouble shooting and repairs. The mechanism of the super reliable roller follower magazine is shown, along with rare factory manuals and accessories.
