lightweight, slim handrail suggestions

[jfornelli]

Looks like I misunderstood what the keymod system is all about.
It seems it is a way of attaching accessories via specially shaped slots in the rail itself, so helps reduce weight.

I had thought it was how it connects to the upper receiver. I had only looked at the Mega Maten keymod (http://megaarms.com/maten/upper-receiver...en-keymod/) which does use a proprietary connection.

So, if it's just referring to the attachment slots, then that Midwest Industries SSK-Key Mod would be cool, as would this one at Parallax Tactical (though it's a few oz heavier): http://parallaxtactical.com/collections/...rettyPhoto
