I have 2 builds on Anderson lower. I used CBC industries Rifle kits. I have one in 556 and 76239. No problems so far. They are not the most accurate ARs out there. As in Moa, I am sure if I spent more time and better ammo and maybe higher magnification scopes. I could be better, but I don’t care about sub moa on plinking AR.
For the price they are money.
I put a refurbished Nikon M 1-4.5 and their rings on and still under 600$

All of them do something better than the 30-06, but none of them do everything as well.
