just built my first roggio. no major problems. the reciever extension tube threads were tight,as i was advised they would be, but using the tube,and some lube,and some back and forth, they loosened up enough to turn by hand. at no timre did they feel like galling. the selector and takedown/ pivot pins were tight, but not excessively. all in all,as good as most, better than some. i'd do it  again, for the money.mine didnt have the "unfinished" machine marks in the trigger well. i'd give it a A.
