Took it off and replaced it with a Troy Claymore. The Claymore over gassed it a hair more, but no issues. The KX was a little better in blast diversion, but not worth the hassle. Going with a flash can that has more than one hole in the front is usually better, unless you have firearm that is under gassed, then the KX would be better.
The lightest option is going to be a KAK. They are made out of aluminum, however they are basically a KX flash can without the front cap. Still works for blast diversion, just not as well. I say try a KAK first because they are pretty inexpensive.
Edit - I see KAK also has a blast converter that has a front cap, with multiple holes, made of steel.
