    Guessing broken ejector/spring.

    ADDED: I am guessing ejector because it looks like your fired case is not being thrown clear. My thought is it appears as though the bolt is going through cycle and the extractor is pulling the case from the chamber, and is perhaps being "shaken" off the bolt face by recoil, but not being ejected to the side adequately. Couldn't hurt to take the bolt apart completely and give all componentry a good going over. Also, can't help but notice the shell deflector has no brass smear at all. Looks like it hasn't cycled correctly from word one, or your really diligent at cleaning it!

    Does it always happen, sometimes, with certain ammo? I would look at the extractor also. Is the case mouth smashed out or round?

    Case mouth is probably smashed by the bolt trying to close on the spent case that didn't eject not by a malfunctioning ejector.

    Pull the bolt and examine if ejector pin has spring tension.
    Then examine if extractor claw is chipped or ejector has poor spring tension. See if extractor will hold case in place in bolt face.
    My take is extractor is at fault and doesn't hold fired case in place long enough for the case mouth to clear the ejection port.
    I've seen steel cases ruin AR extractors.
    This problem can also exist with weak loads or worn gas rings.

    Have you checked for full bolt travel? Looks like this may be a new rifle?

    more than likely, you have the wrong buffer in it, causing bolt bounce. very common problem when people switch uppers or buttstocks and buffer tubes. I would make sure it is the correct buffer first. that is the most common problem I run into on ar15. very few extractor problems. also, make sure your gas key on the bolt assembly is staked tight and not loose, it will cause the same problem.

    There are several grimlins that cause this problem.

    The buffer, and spring not matched to the gas system, gas rings on the bolt that are worn, broken, ejector spring, or something hanging up the ejector.

    One more thing, not all rifles, or AR's are created equal. Century is known for problematic AK's, when 3rd world countries can build them flawlessly by the tens of thousands. If they can screw up an AK, then they can surely do the same with an AR.

    Your rail looks like a banana
    Is the upper warped?

    That's a lens aberration. Short focal lens, close focus distance.

    Your extractor appears to be working fine.
    Check ejector spring strength or bolt ring tension.
