    Not sure how or why an anti-tilt carrier would increase accuracy or help anything in a DI gun. A piston AR is another story.
    The bullet has left the bore before the carrier begins it's rearward movement, correct? I believe this to be true with most common AR-15 barrel lengths/gas system lengths. Not so sure about 26'' space guns.
    Also, there is inherently some wiggle between the bolt and bolt carrier. Slight. So even if the carrier had zero tilt and rode on linear bearing rails, the bolt itself could tilt ever so slightly whichever way it wants to. The ejector's/extractor's pressure on a chambered cartridge might pre-load(tilt) the bolt to some extent too. I guess this could be effected by cartridge headspace.
    Finally, let's say the carrier is moving rearward just before the bullet has left the muzzle, a mm or two, wouldn't the tilt be the same each time and therefore not hurt accuracy?

    Not to be sarcastic, but the same is said about barrel break-in, and there is no consensus on that, at all. Some swear by it, while others swear at it.

    I'm curious as to what kind of wear (If any?) those screws he put in add to the rifle.

    Given the experience of the man in the video, I will give his opinion weight. I have had several match rifles that would easily shoot 1-1/2" groups at 300 yards off the bench without addressing the issue of bolt carrier tilt.
