Well guys I finally got to the range today with my new AR build. Simply put, I love it. Put 90rds down the pipe, 60 assorted steel, no problems. I got a combat zero at 25yds then stepped it out to 200yds for some fun.
Here is Linuxuser3890 shooting at 200.
We put some of our rounds thru a chronograph to see how consistent they were. Average was 3031 for the brass, 2850 for the steel.
I'm very happy with this gun. You can feel the difference between the mid-length and carbine gas systems. I think I'm sold on the mid-length.
