Hey folks, would like to hear from the bushmaster owners regarding what flip up BUIS fit best on the rail. I just picked up a Troy flip up rear sight on EE and it won't tighten up enough to secure firmly in place. It will however tighten up on other rails I own. I just noticed that there is a very minor difference on the bushmaster rail. On a side note, I have a mint Troy flip up rear sight for sale that will be on EE shortly.
