Stompy Posted November 1, 2010 Share Posted November 1, 2010 I have had my M2 Tactical (ghost ring sights) for 3 years now (a little over 1000 rounds) and I noticed the front sight has gotten a little loose and I can now move it from side to side. Should I use some blue loctite to lock it down? What is the prefered tool/wrench to use? I had it dialed in to hit gatorade bottles at 100 yards with slugs too.

cody6.0 Posted November 1, 2010 Share Posted November 1, 2010 The nut takes a 5.5mm wrench, as for loctite a fresh lock nut would be better if you plan on taking it off again. Quote Link to comment Share on other sites More sharing options...
Stompy Posted November 10, 2010 Author Share Posted November 10, 2010 Maybe I am doing something wrong here but I tried turning the nut with a wrench and it would neither tighten nor loosen. It was turning around on the screw but it wasnt going anywhere. The front sight is still loose and I cant get it to lock down or even get the sight to come off completely because the nut wont loosen of the screw?

Hookster Posted November 11, 2010 Share Posted November 11, 2010 Here's a source for a new nut http://www.brownells.com/.aspx/pid=23654/Product/FRONT_SIGHT_RETAINING_NUT Stompy, I don't know what is wrong with yours but if it won't tighten you might be able to use a dremel and very carefully cut the problem nut away and replace it Hookster Quote Link to comment Share on other sites More sharing options...
