The front sight is secured with a key and the pin. Moving it is going to take a bit of work.
You are going to have to remove the front sight to install your barrel band with lug. Even with a 18.6" barrel, a bayonet isn't going to fit. It was only at the very end of WW2 that carbines started appearing with the bayonet lugs.
The plum colour is just a result of the bluing, doesn't mean anything with respect to receiver quality.
