Knights Armament Ras Quadrail Handguard

[BenKenobi2]

Does anyone have one? Would like to put one on my Colt M4. If you have one PM me.
I need the model that is a drop in for carbine length, I believe its 6.8 or 7" inch handguard model.

Thanks!

I'm not too sure but @TacticalJeebus might have something of that nature. He has some of good stuff
