Never owned one and some how this doesn't look right but no matter how I try and take it apart I can't make it look right as I don't know how it is supposed to look. An there is no close up in the owners manuel. It fired the primer fine but I'm going to site it in in the am as was just concerned. Just looking for some info or a close up of what it is supposed to look like. I tighted everything and even tried to loose to align the nipple nd it doesn't go, making me think this is the way it supposed to be. To my thinking the niple should be turned another 1/4 turn tighter to align all the groves and nuts.
