New AR carbine (DPMS), 55 grain VMAX with 25 grains of Varget, WSR primers...2650 FPS over the chrono today? Isn't that a bit slow??? I was expecting closer to 3000 FPS. It was accurate though, iron sights at 100 yards printed a 4-5 inch group of 40 rounds. I'm guessing it would be a 1" group with scope. Haven't shot an AR in 13 years.
