Personally, I found the "C" sights too low for me to use with goggles on. The sight bridge has a functional scope and it's pretty good too (I've found the G&P version to be better than the STAR one) and there's an "iron sight" as such on the top. It's not adjustable and you have to paint some white dots on it to use, but I found it works well for me. G&P also makes a complete foreend conversion witht he foreend, rails, barrel extension and muzzle break.
