I agree, but the m4 is where it's at for me, until something better comes along.
Some of the new 5.56 stuff is really nasty, as well, terminally. The 62gr Dual Performance from Black Hills is up for evaluation for me this deer season. Last year mk318 mod 0 was the top performer terminally, but groups 2.5moa while the dual is running 1.6-1.8 for me. 10 shots at 100. Also, I love black hills qc.
