I bought this for a 4sevens maelstrom X7 and if you leave the roll/lanyard ring on you can hang it from that in stead of the head of the light for a more comfortable fit :) I used some black leather strap to make an extension for it to reach my belt (custom fit lol) If you want to cut the extra leather strap from your shoulder rig you could use that as well. I stiched mine but you could use velcro or leather glue or even buy a snap kit ;)
Pros: Holds flashlight very secure is adjustable that way
Cons: If you wear your rig high you cannot attach it to your belt(tie down)
