The Chamber True Centrering Unit will ensure a snug fit to restrict the motion of the outer forces the chamber/ inner barrel perfectly on the horizontal axis. It will center the inner barrel and keep it steadily locked in the true horizontal position so even when shots are fired, which is the moment where there is the most stress and vibration at the hop-up, the structure stays intact. This in turn will create a dependable system for the BB to travel down the barrel undisturbed for the most consistent and accurate shots.
