I had mine out recently, but only had time to shoot about 120 rounds of various cheap stuff (all .223, rifle is 5.56 chambered). Not a huge sample size, but I had zero FTF or FTE. CPD metal 10/10, MFT polymer 10/10, CPD metal 5/30, and the Hera 5/30 mags all worked without issue. No issues with pins walking out and I didn't find the trigger particularly awful (might speak more to my inexperience with after-market triggers). Did not perform barrel break in. RIP accuracy.
My rifle doesn't have a charging handle magnet (guess I'll have to ask Kodiak for one) and the inner left-side of the upper receiver is showing some wear which may be related to that (as compared to the right side). Most of the fasteners were loose when I first opened the box, nothing a few tools can't fix. They stopped using the plates with the sling attachments, I guess that was the trade off for the nicer stock. I also found the back-plate/takedown-button to be very tight in the upper receiver. Generous lube helped, but the first time taking it down was a chore. Also, the thing with the rail and the Magpul rear MBUS; had to shave down the bottom of the release levers on the sides.
Overall, good rifle (at least my copy). Happy with purchase.
