I just got back from sighting in my new M4.  My Aimpoint sighted in with a Max.of 8 clicks either up or right-no problems.  When I went to sight in my ARMS 38, the rear aperature (sp?)needed to go almost the whole way to the right.  I know BM is notorious for overtorquing a pin during their uppers assembly which may cause this problem.  It looks like my front post may also be bent.  Is this something that needs fixed or is it just an annoyance.  Once it was adjusted, accuracy was fine.  TIA, Jim

Just an annoyance.  But if you want it fixed Bushy will do it.
