Colt branded A.R.M.S. #02 M16A1/A2 carry handle optic mount. There are a couple of variations of the Colt branded A.R.M.S. #02. Still hunting for the other one.

Do you have a source for these? I’m trying to locate 2 for retro builds, I’m only able to find picatinny ones.

I do not have a direct source. You can find them on Ebay and Gun Broker pretty easily.
