You need 1/16 roll pin punch; 3/32 pin punch and bolt ejector assembly tool.
Young Manufacturing ejector tool is best.
It positions bolt by one of it's lugs so that roll pin is in vertical orientation. Compress the ejector and use 1/16 roll pin punch to tap out the pin.
To assemble, use roll pin holder to start the pin in and then tap it home with roll pin punch. You may use small needle nose pliers if you don't have pin holders.
To remove extractor, compress the part of extractor where the spring is located with your fingers and push the pin out with 3/32 pin punch.
Pin is slip-fit and easy to remove.
The extractor springs do come with black inserts.
I recommend Colt ejector and extractor springs. You may purchase them from Specialized Armament.
Good quality and inexpensive roll pin punch is Mayhew (U.S. made).
