||This site is good. One thing you will absolutely need is a set of small alen wrenches. instead of pins, ECHO1 uses screws to hold this site in place on the barrel. this makes it extremely sturdy as long as its set up the right way.The actual flipping system is not spring loaded but when flipped up, it stays in place very nicely due to a small metal rod that keeps it in place. flipping from up to down and vise versa is very simple The only thing I don't like is the paint job. its horrible. after little use, paint started chipping off it. easily fixed with some krylonn ultra flat though. This site works great on my CA and looks awsome (CA CQB compact) Its a really nice site for the money.
