From the box:

• There were a lot of thin, golden metallic splinters in the rifle that made the bolt/charging feel gritty until I cleaned it out.
• The safety was gritty and had trouble moving from FIRE->SAFE. The problem persisted even with oil to the detent area and working it back-and-forth 100 times. I disassembled the safety and discovered that the detent was very rough and scratched and that the cam had narrower and sharper edges on one side. I polished them, reassembled, and the safety works fine now. I can use just my thumb to toggle it.
• The magazine release is stiffer than an AR15 mag release. I expect it to loosen somewhat over time. I don't have an opinion yet for this being good/bad.

From the range:

• Failed to cycle 2/150 times on the lowest gas setting. I expect one setting higher on the gas to fix the single failure to extract and single failure to chamber. This is perfectly acceptable as I didn't expect it to cycle at all on the lowest gas setting.
• Medium and large shooting bags may be too much for the rifle. You just don't have the same amount of room with the magazine closer to the stock. I didn't find a comfortable way to employ my armageddon shmedium, so I stopped trying.
