H2O Man, What is the weight of M21A5 CH EBR SASS?

And, what type of range results do you get from your M21A5 Light RRM (@ 100 yards)? I'm just finishing up the upgrades to my Polytech, which is somewhat similar. Knowing what others have shot serves as a guide and is really helpful.

I'm am just waiting for the snow to melt so I can get out to the range. More snow is coming tonight. I'll let you all know how it goes at the range once I get out to it.
