Sorry forgot to add that part in there lol.
What I was told is when You have a barrel to reciver fit that is lose as in you can wiggle the barrel by hand when its in the reciver (before you install barrel nut of caurse ) that applying blue locktite to the barrel extention will fill that foid when you install and tighten down the barrel nut giveing it less chance to flex when a shot is made. And increse accuracy.
I have seen it work first hand with the first grendel upper I had, I also had to lapp the reciver face on that upper as well and that seem to help the groups as well.
What people told me is true the most important things for accuracy in the AR is barrel and trigger and lots of trigger time.I have seen these lil things we are talking about help out as well.
So I did them on my new upper.
