In this video, I show the effects of different action springs and buffers on the three phases of AR-15 recoil, using a BCM 20″ upper for demonstration purposes. I've copied the text from the video here so that you don't have to wait 60 seconds while it scrolls by on the screen if you don't want to. There are three distinct phases of rifle movement immediately after an AR-15 is fired. The first phase is what most people think of when asked to describe "recoil". The projectile exits the muzzle, and the weapon pushes back against the shoulder of the shooter. Depending on the choice of muzzle device, the muzzle may rise, drop, or stay on target during this phase. The second phase is when the bolt carrier group reaches its rearmost point of travel. This generally causes the weapon to push back against the shoulder of the shooter, and the muzzle to rise, regardless of muzzle device. Depending on the gas system, buffer, action spring, and other factors, this may be reduced or eliminated. The third phase is when the bolt carrier group travels forward and stops after hitting the barrel extension. This generally causes the weapon to come forward, away from the shoulder of the shooter, and the muzzle to drop slightly. Depending on the gas system, buffer, action spring, and other factors, this may be reduced or eliminated. In this video, the first phase is very similar throughout. An A2 muzzle device was used for all videos. Pay attention to the movement speed and direction of the <b>...</b>
