Thanks,..... expensive is right - I took the new AR to the range this am and burned up $80 of ammo, but it was FUN

Once I had the scope zeroed I started plinking at a 9" steel gong at 100 yards - it was not really challenging enough, I may have to move it out to 200yds. I also tried out the used LMT 10.5" upper I picked up on the EE. It cycled perfectly, which was a relief as someone had warned me that I may need a heavier H2 buffer. I think the extra weight of the LMT Full Auto bcg may have helped ??
Here it is with the LMT upper:
