    Just to be clear, am I to assume that the standard 9.3" will NOT properly fit a mini or micro upper then?
    Thanks again for your patience.

    It will fit.... BUT, on a mini upper, you won't be able to reach the gas adjustment. On the micro there will be some exposed gas tube, about .3" more than with the micro gas system.

    Can the gas adjustment be manipulated by bullet tip or simple tool, through the vent holes? On the gunbroker pics it seems to show it even more recessed in the standard upper. Surely it can be turned inside there?

    The dial was designed to be manipulated though the vent holes with a bullet tip or similarly pointy item. If you put a 300 standard length barrel on a MINI upper, you won't be able to reach the dial. The vents are spaced differently. Both systems will work on the micro because the gas block is exposed.

    I'll take the 5.56 Light 1/7" twist 16" barrel and a old style 5.56 bolt.

    I've got some 9" 300blk mini conversions coming in the next week or so. Micro 7.5" are just behind those. Let me know if you're interested.
