Have you ever wondered how the AR15 works? How does the reciprocating Bolt Carrier feed the rounds from the magazine exactly? How does the trigger group function and reset itself after each shot? How does the gas system operate to bleed gas out of the barrel and to operate the bolt carrier? This video from 45Snipers answers these and other questions. This 5-minute video uses “cutaway” computer animation to show all the features of an AR15 from the inside out. This fascinating firearms video allows the viewer to see inside the upper receiver, lower receiver, bolt carrier, chamber and barrel.
This video is slow to start and has annoying music in the background, but it’s worth watching if own or shoot an AR-platform rifle. This video shows all the key actions during the charging process, loading, firing and ejection. The cutaway animation demonstrates how rounds are removed from the magazine, and then chambered. The animation shows how the trigger group functions and how the primer is struck by the firing pin. You can watch the bullet travel down the barrel, before the empty shell casings are removed from the chamber. Here are some sample frames from the movie:
