OK Apparently I was wrong I just checked and T/N stands for Titanium Nickel (Or Titanium Nitride???).
And may or may not be the name of a company as well.
Also yes the suppressor will make the BB exiting the barrel quieter but to get rid of (minimize) the "sewing machine sound" you'll have to do gearbox work. Sorbo Pads, Shimming, and Correct Motor Height will make it even more quiet.
