Attaches fine to mine.
Remember to get the grib, that allows attachments, standard version do not.
Information on the standard grib is not very clear tho.

duct tape does't work.

^I know the duct tape solution was probably meant as a joke, but... well at least for the flashlight it kind of makes sense, doesn't it? Maybe that should be added sometime in the future?

not a joke. I heard Dean say you can use duct tape to attach flashlights to weapons in his stream. But yea I think you need an RIS on your rifle to attach a flashlight to it.

You do need a different grip for the rifle for this to work. Finally found it.
