BTW, do you happen to have weight of your rail with and without the barrel nut?
I did a full review for the HK guy... HK416/MR556 Geissele Rail

The HK rifles already have the same type bbl nut that will come with the AR, but not sure of the weight of it. I personally don't notice the extra weight from the added length (+5.5 inches) probably because it's so slim and comfortable to hold. Then again, it's an HK and known to be on the heavy side of the M4 variants. So I'm used to it.

I did do the math when comparing the stock 9 in HK rail to the G-rail per inch and the Geissele rail was .2 oz lighter per inch. That included the QD that's already built into the HK Geissele rail. My guess is that the AR will be slightly lighter than the HK version.
