I would like to hear comments on POI and tension on the takedown screw. I installed the o ring on the screw right out of the box along with a AT3 Tactical RD 50 red dot. After zeroing and shooting for about 3 weeks all seemed well. During that time I took it apart for cleaning twice. I shot it on paper off sandbags today at 25 yds. only to find it shooting 1.5-2" left. Tightening that screw against the o ring feels a bit squishy to me so I'm wondering if I'm geting the same tension each time or if it dosn't matter that much.
