Looking Great TEG! Which one do you like better so far?
I prefer the looks of #1 with the stock Ruger hand guard. The rails on the #2 4" hand guard look out of proportion to me somehow, however I do like the folding vertical grip and shorter 0/A length (26.25"). I have not shot the #2 configuration yet, but i did shoot it with just the bare 8" barrel and no HG, I think I will prefer config #2 for shooting.
Configuration #3 will be similar to yours, only shorter, will be the kinetic-tech shroud and a 4" smooth round HG. I like the MP5ish look of that set-up.
