mmccall60, does your rifle look like the above photo ?
or this:
"How do you remove the Forearm Rail panels in order to add other components to the rifle?"
you see this is what is confusing, if you have the one in the first photo you do NOT need to remove anything, just add on whatever you want, if it is the bottom photo, you are pretty much S.O.L.
can you post a photo of your Colt ?
