I'm grilling you like this because I haven't heard much about that optic. How much did you pay for it?
You need to get thy ass off tha bench and do some offhand shooting. You need to heat the gun up to see if anything breaks, so during "break in" some rapid strings are good to get stuff hot.
What's your bolt look like? MPT/HP? Black extractor insert? Five coil spring?
Does the upper have M4 ramps?
You posted a pic of the gas key on the bolt carrier.
I have no idea what any of those things are as far as extractor inserts or 5 coil springs. I dont even know who made the bolt and carrier. I got it from an old guy sitting at a table at a gun show. When I asked him who made it he looked at me like I was from mars. But for 75 bucks I figured I would give it a try. So far I have not had any problems with it. I am relatively new to this so bare with me.
