    Seems a two part solution would be best for this.....the XCR's rail is super thick by AR standards....maybe hog it out while reducing the size of the gas block somewhat. But....looks like the current idea of a smaller block must be within parameters (based on PurpleNurple's pics).

    I only use 220gr subs when testing. I have both mini and micro length gas systems and both run fine with a can. The gas ports were drilled out tons trying to get them to cycle without a can, the hole doesn't need to be that large for running supers normally and subs with a can. I know Alex was working on a smaller block that would go up under the rails but I can tell you that having been shooting 300BLK for 3 years I don't ever shoot my AAC without a can when shooting subs (and it will cycle them just fine).

    I don't think most guys will want to buy a new upper/rail to shoot 300BLK on their L. With the SIG Brace I can see more guys running micro uppers but guys want to be able to purchase a barrel and convert.

    Agreed....which is why hogging out the rail wouldn't make sense....and consequently why miniaturizing the gas block to fit under all rail configs would.

    That's not how things are done here. We don't need nannies. Take what you want, leave the rest. If you feel the need for lots of moderation, you're in the wrong place.
    It's not that nannies are needed, it's that we have two sides of this thread, one a teaser and informative about rob arms and 300 blk another a flame war between two parties that in part hijacked this thread and detracts from its purpose. But my comment was mostly a joke.

    we like the flame wars around here... that is NOT what makes us like any Forum or US Government Entity, because we let the flame wars continue, but at the end of the day we shake each others hands and treat each other to some beers.

    Gun guys (95% of them), are no different than liberals. They want to be governed.
