Smyth Busters: Is a Tight AR-15 an Accurate AR-15?
This video busts the myth that a tight fit between the AR-15's upper and lower receivers is necessary for accuracy. The Brownells Gun Techs explain that the critical components for accuracy, such as the barrel and sights, are housed in the upper receiver. While a loose fit might affect the perceived quality or cause issues with certain accessories like monopods, it does not inherently impact the rifle's ability to shoot accurately. The myth is debunked by highlighting that the lower receiver has no direct role in the bullet's trajectory.
