Pusj\h pin installed. Was an original 6551preban Sporter. Has removable block, small front pivot pin and large trigger pins. Sorry I do not have digital camera. Only marks are on magwell from loading. Looks great.
Drilled, means that it is factory drilled for the detent/pushpin pivot. You can tell by looking at the mag fence, on the raised metal that is inline with the pivot pin and if there is a tiny hole in the side, it is drilled.
