Problems with custom parts Be aware that custom parts are not guaranteed to fit and may require some modification. If you decide to replace stock parts with modified custom parts it can lead to the AEG being altered in such a way that the modifications cannot be reversed. Barrels and hop units Barrel performance is not necessarily related to length. For example, an ICS CXP has a range comparable to a full-length G3. If the barrel is too long then the BB experiences more friction which can reduce velocity and range of shot. Fitting a tight-bore barrel can improve the grouping of BBs and therefore improve the accuracy of your shots. But this can also increase the velocity, which can be a problem on AEGs that alread
