Well, better late than never! Here's my first range report with my new M&P15 Sport.
I bought my M&P15 Sport on October 11 and just took it to the range today. Work has been crazy! I fired 120 rounds through it. 55 grain ball from Remington.
It took 24 rounds, using 3 shot groups to zero it at 100 yards. Ultimately, I adjusted the elevation down about 5 clicks and the windage left a tad. I went back and forth a couple times, left and right, to make sure I was maintaining a consistent sight picture. I shot from the bench with my range bag as support. At the end, all shots were in the 10 or 9 ring and I was satisfied considering the support I was using and a slight wind.
I fired another 100 rounds sitting supported and standing unsupported. The rifle ran great. No feed or ejection problems of any kind. I fired both fast and slow paying attention to how the rifle cycled. I used 4 different Magpul P mags.
Overall, a great range session! The gun functioned as it was supposed to and it felt great.
