I am building a 97 from parts,I have all the parts except a few,which are on the way,I am puzzled on the ejector,in the nra parts exploded view,it shows an ejector spring,I can see where that goes,but there is a t shaped part called a ejector pin,where does that go?also on the take down,it says to turn the mag. tube and pull it forward about 2 in.what about the action slide,does it just comes out,or does it have to be disengaged some how ? these 97s are a bear to put together.thanks ahead of time :toast:
