| Just bought a Rock River 14.5" M4. Anybody have any grouping data at ranges out to 300+ meters. I know it's not a long range varmit rifle, just curious. |

Scar, Was just out on Monday testing my 16" chrome lined M4gery by RRA using a 2x TA47-2 Compact ACOG. At 400 yds I was getting 6", at 500 yds = 9" and 600 yds ='d 10" groups. My ammo was my own make using the Hornady 75 bthp Match going 2720 fps. Yes, that NATO spec speeds. As I said, my own make! Big Al |
