I currently own a Bushmaster Carbon 15 (don't worry it's my spare rifle).  The problem I have with it is as most of you know, it has no fixed front sights.  What I'm looking for is a drop in handguard system that will allow me to attach flip up sights or 45 degree sights.  I have a quad rail on it now and the rails are way too low for flip up sights to properly work.  Is it just bad quad rails or do I need to find a different solution?

what sort of rear sight do you have?








Do you have the Carbon 15 Optics ready carbine?
 


Do you  have a front gas block with a rail on top of it?  then pick one of these appropriate sights, http://www.bushmaster.com/products.asp?cat=19

Look at replacing the entire BM upper with one of Palmetto State Armory's Black Friday Uppers $179-289.
Sell off the BM for whatever you can get and you would probably be way ahead of the game.
