Okay so i've had my MBUS for awhile and it works so far but it looks cheap and I wanted to try the Troy "Di-optic" sight so I ordered one online. Then I came across this article. http://kitup.military.com/2012/07/back-up-iron-sight-drop-test.html It seems to suggest the MBUS are actually more durable and hold zero much better. I don't want to downgrade my equipment even though I just use it at the range or the woods on my friends land but I tend to run my stuff kinda hard. What is your opinion on these two sights is the Magpul really better or is it just luck of the draw that it held zero better than the Troy? Anyone try the "Di-optic" aperature and like it better than the normal peep? I'm probably gonna get a .22 AR and put one of the sights on it but I thought I'd put the Troy on my 5.56 cause it would be a better sight i'm just not so sure now.
