The reliability seems very good. I have 550 rounds through mine. My only issue was the ATRS polymer mags. Rounds would vibrate and nose dive causing fail to feeds. While this only happened 2 or 3 times per mag, it was annoying. Moving to the LAR15 steel mags completely solved this issue.
And that was the only issue. Mag dumps are invigorating! I've even tried the PCV Beowulf mags with 14 rounds (not 15 because of side flex). Lots of fellow AR shooters looking with envy as I plink away. Accuracy is excellent with under an moa at 100 yards with relatively small optics (1-4x24).
Mine handles very well, with the Fortis fore end. It seems lighter than it is. It shoulders very well and I have a single point sling to let it hang under my right arm. And cleaning is a breeze.
I sure hope the haters stay away because I swore I would never post any type of review because of all the negative backlash when I initially got the rifle.
So enjoy yours!
Edit: I'm using Black Hills match 77gr SMK ammo.
