slowhand23 Posted August 12, 2012 Share Posted August 12, 2012 Hello All, Took over 1000+ rounds but HiViz sight came loose on my M2. I tightened the screw and was back in action but read some install roll pin in rear for permanent fix. Appears like a tight fit so looking for some pics. Assume it's a 1/16" x 3/16"? Original install had some adhesive as well. Appreciate any help. Link to comment Share on other sites More sharing options...
mike cyrwus Posted August 12, 2012 Share Posted August 12, 2012 that pin will work. Use a starter punch and do just barely aft of where the copper leaf spring is swaged into the sight. Make sure youre squared up, a press or mill makes it easy. Link to comment Share on other sites More sharing options...
slowhand23 Posted August 13, 2012 Author Share Posted August 13, 2012 Thanks Mike! Just to confirm, the pin is under the fiber rod? Link to comment Share on other sites More sharing options...
GunCat Posted August 13, 2012 Share Posted August 13, 2012 The 1/16" diameter blind pin sets about 1/32" or less above the plane of the rib and fits up into that hole in the sight body (yes, its under the FO rod) Link to comment Share on other sites More sharing options...
