Lightest hand guard yet?

[Tedward]

I've been using SLR keymod HGs and they might me lighter than those and use a standard wrench to put them on. Also a little more coolness to the look. I'm using them with 18" fluted barrels and you can feel the weight difference big time from non fluted barrels.

Now I will be getting a scale to do weight comparisons. Any brands of scales recommended for weighing parts like complete uppers? Or lowers with stocks?
