another "which upper?" thread

[damndave]

Would something like 4-5 MOA be too much to expect from 55 grains out of a 1:7 twist? I'd like my setup to be able to hit COM on a human size target from 100 yards.

On a 1:7 and 55gr ammo you can get 2-3moa rested without much issue. It will stabilize just fine. Don't let the twist rate deter you from a particular upper. I shoot 55 and 62gr ammo out of 1:7 and 1:9 and have not noticed any accuracy difference in my 50 or 100yrd groups.

Didn't even fully read the OP's question. Just skimmed through it and saw BCM as a choice. Get a BCM upper. Even if it costs a little bit more than the others its most definately worth it. Save up if you have to.

I currently run a Noveske but I have heard that BCM is top notch.
