Troy drop in battlerail weight?

[mastiffhound]

I've been looking at drop in rails for my rifle length PSA in 5.56. I have a 1-piece Troy 11" free-float Battle rail that I like alot. I like how Troy's drop-in rail systems use screws and lock up tight. Nothing drives me crazier than moving rattling gun parts. I don't know what the weight of the Enhanced or regular Troy drop in rails weigh though. Troy doesn't list the weight, which might mean to me that they are stupid heavy? I can find what some have listed on the net but they are for carbine and mid-length, of course that doesn't help at all. Do any of you have the rifle length rails and have you weighed them? As always, thanks for your help!
