She shoots great. My torque wrench is a 1/2 drive, about 16 inches long kinda like a breaker bar. (more like a break stuff bar..haha) One thing I was impressed with was the M4 feeder ramp notches in the Del-Ton upper. They lined up perfect with the ramps in my barrel it looks like they were cut together. Also the dust cover has a perfect fit when closed (very nice)
