[ARCHIVED THREAD] - Sight issue

Posted: 9/20/2012 10:56:51 AM EDT

I am currently using a Troy fixed font sight on a 12" MI Gen 2 rail with a Matech rear sight. I sighted this combo in when the forearm was still a specter length forearm and it worked fine. Then I changed the forearm to the MI and at 25 meters (sighting target) it now shoots 1 and a half feet low and I can't spin the front sight any lower....any ideas??
