I want to add this to my Bushmaster pistol, ideally under the barrel so I can still mount a red dot on top, I have the one with the silver flutted barrel, I would love to be able to do this via a 2-4 rail metal handrail but I am still to find info on one that would fit it, if some minor machining is needed to be done on the handrail it is ok or any other way that I can get this flashlight laser combo on this handgun will be appresiated.

The M6 is mounted via a built in mount for a picaniny rail but I believe that there's a model that comes without the mount, will I be able to use any of this Bushmaster parts instead with that version:

I DO NOT WANT TO DO THIS BY GETTING THE BUSHMASTER KIT THAT WILL CONVERT IT TO A NEWER VERSION WITH A LOWER AND UPPER RAIL AND THE FOAMLIKE BLACK HANDRAIL.
