You will not find a better or quicker mount to fit your tracking light on the rifle! Just strip it on the flashlight and then around the barrel or riflescope so it sits in place. Very stable and good. The Velcro is very powerful and easy to tighten properly, the rubber mount that holds the lamp and the barrel / rifle scope adapts aoutomatically to their dimensions.
Quickly mount without tools, no risk of damage to the gun or rifle scope- perfect fit!
Pretty good that the rapid assembly allows the tracking light to be used as an ordinary flashlight until needed on the weapon.
Buy one and try, you will be amazed how good and stable this is! Do you have a long and heavy bulb, use two brackets.
