Here's a link to my first range report - with a picture of a target when sighting in my scope at 75 yards:

That’s what I’m hoping for!! I’d be happy lol. I just ordered the 16 inch. Now to figure out a magazine.
Thanks everyone for the help!!

Unfortunately, the gun would not cycle, feed or eject! I tried all the tips I found on this site and nothing worked.
Finally decided to take it apart and measure the gas port. It was supposed to be .076" per specs but was actually .067". I stepped it up to .0785" (#47) and put it all back together.
Range results were absolutely perfect! Ran 80 rounds with no issues, ejected all 80 in a nice pile around 3:30/4:00 position. Accuracy with the Leupold 450 CDS Scope was impressive.
I would buy more from BCA but I would be ready to inspect carefully. I really should have returned the upper but I don't mind tinkering a bit. For my needs as a casual shooter/hunter BCA fits the bill just fine. Good luck with yours!

I will say, drilling should be your last resort. There is plenty of info on the forum for what else to check before voiding your warranty by drilling. Sending it back would be the better option for sure. But let's just be hopeful you won't have any issues at all! Let us know how she shoots when you get it in hand.
