Not having much firsthand experience with either manufacturer, is there any significant difference in a Troy BUIS vs a Midwest Industries BUIS? I can get a Troy front/rear folding sight combo for $199. http://stores.homestead.com/Laruetactical/Detail.bok?no=203 Or I can get a MI set for $150. http://www.m4store.net/index.php?p=product&id=121&parent=33 http://www.m4store.net/index.php?p=product&id=124&parent=33 I hear people raving about Troy, but I don't hear much about MI. So I was just wondering, is the Troy worth the extra $50, or is one just as good as the other?
