Factory load performance in the M&P15

[arizona98tj]

Anyone find any .223/5.56 factory loads that shoot MOA or better in the M&P15?

I've tried a handful of different 55 gr factory loads but haven't found one that stands out yet that the rifle really prefers. None have hit the 1" mark yet.

I guess the number of M&P15s out there must be highly exaggerated.
