Can anyone please tell me what the exact weight of the buttstock (MSR Stock) on the Ruger Precision Rifle is? I have been googling this all night and so far it is not posted anywhere.

Without buffer tube, end plate, and castle nut the assembly weighs ~21oz on my postal scale. You should be able to find the weights of the AR parts, I don't have them on hand.
