I have a Surefire Ryder9-Ti with direct thread nielsen device. I'd like to be able to use the tri-lug on my MP-5 clones. Does such a modification exist that I could buy a tri-lug mount and have the Ryder fitted to use it? Surefire made an MP5 version of the Ryder9 with trilug, but I'm not sure if the can was different and they tell me their mounts are no longer available anyway. Thanks!
