lightweight, slim handrail suggestions

[Schwag173]

I'm looking to get a handrail for my 16" build. It will be used for hunting and I don't feel the need for too many picatinny rails. My primary concerns are that it be lightweight and slim. Perhaps a slim carbon model?

AP Customs all the way. I've built 2 5.56 carbines and one Grendel with them. They are damn near weightless and give you the option of some or no rails.
