Picked up my my new Nikon M-223 2-8x. Put it on my Daniel Defense M4V1 LW. Went out the other day with my new Lead Sled to put some rounds down range. Found out my gun prefers Federal 55-grain 5.56. At 100 yards shot a 3 round group at .325". Very happy with the results. How do you guys like your nikon M-223??
