Ohioguy Posted July 20, 2020 Share Posted July 20, 2020 (edited) Rear sight set screws. What size Allen key? I have tried a set of both metric and sae Allen keys (brand new), and I cannot find a key that fits. The one metric that sort of fits is so loose I will not attempt to use it for fear of stripping. Gun is new, never been molested prior... Edited July 21, 2020 by Ohioguy Link to comment Share on other sites More sharing options...
KlausN Posted July 21, 2020 Share Posted July 21, 2020 2mm Allen. The fit is somewhat s#!tty on mine too. I had to heat up the sight using a hot air gun to “liquify” the thread locker on one gun, the other was very easy to unscrew the grub screw.

KlausN Posted July 21, 2020 Share Posted July 21, 2020 The actual screw should be a M4x6 Socket Set Screw Link to comment Share on other sites More sharing options...
Ohioguy Posted July 21, 2020 Author Share Posted July 21, 2020 Thank you. I will pick up some replacement screws. Think I will get an ez out (if I don't already have one). The fit on these is atrocious. Link to comment Share on other sites More sharing options...
Csexton Posted August 12, 2020 Share Posted August 12, 2020 I agree. I had to shift my rear sight ever so little. But, it was an act of god to get it to move. Well, maybe not that bad. But, I did have increase my hammer size and use a bench block. I was going to heat it as a last resort. But, a little more pressure did it. In hindsight, I say just use a hair dryer and get it good and warm. It should melt the lock tote enough and make it much easier to move. Link to comment Share on other sites More sharing options...
