I agree with other review that these clip be tight . that be nice for hold the light , but I also agree that if you alignment be off too much it lead to premature failure . once again it would cost they nothing to include a small template strip of paper . little fold mark for 2d , 3d , 4d , 6d , whatever , would make it universal for any d maglite . this be a theme with I and my review - stupid thing like this cause product failure and bad review . maybe that be what they want to sell more bracket ? either way I order more set . I be not go to let they stop me from send they my money : p
