Okay so I got this halo in part of a trade, and something is messed up, but I'm not 100% sure what it is. So I'm thinking the problem is in the shells, but here is the issue, a lot of the screws aren't reaching far enough to screw into the nut on the other side of the shell. The two shells clamp together completely on the outside, which just doesn't seem to make sense why the screws won't fit. Any guesses?
Onto my second problem, I have a speedfeed of some sort, but I have no idea how to put it on. I'm guessing I'm missing a piece or something. I just cannot figure out a way to put it on, here is a picture of it.
Thank you, any help is greatly appreciated!
