    If you read the post above, the inner diameter is a little tighter. I have had the same issue with Colt bolts, FN and even the stock LMT bolt was a little tight. In the end it's a non-issue as it runs just fine.

    I obviously haven't tried out every bolt on the market, but there are reasons that I keep a stock of KAC, Colt, and LMT bolts with their accessorize. Until I find a reason not to do so, I'll keep a stock of them over the others on the market.
    Not saying that others are bad, but i'm not convinced enough to have the others readily available at hand.
    Again, not saying others are "bad", maybe I need more convincing?

    How much of a non issue is it really? The stack of tolerances should allow the bolt to "float" without interference during the high pressure event without a vector of force that could drive it otherwise in a non linear torsional matter.
    When the tolerance stack is added up, you can see how well or poorly these components can come together.
    During the initial free cam path before unlocking in the carrier pathway there is no torsional force applied.
    When the carrier caming comes into play, there is an equal force distributed in both planes.
    To keep it simple and short, nobody really wants to waste applied force to hammer and displace material, more should be done to work the action instead of that. The balance of some tolerances in real world scenarios can make a great scene and should not be overlooked.
    While it may be harder to see a reduced stress scenario, it is easy to see higher stressed ones and ways to avoid that to a degree at least.
    I really wonder about those positions with the LMT enhanced carrier and how can that be in a few ways, even with a bolt that could be less than desirable compared to the normal M16 carrier and upper.

    I have used a Knights E3 bolt with no overly tight feel.

    Lube it and run it.

    No, only the bolts mentioned in my previous post. I purchased the carrier only from LMT with the intent of running my own bolt.

    That's my plan. I'm going to try to get a few rounds through it on Tuesday.

    Did you see my post explaining it's supposed to be that way

    Yes. I ended up finding another bolt that was snug but still moved freely and slapped everything back together. After you posted, I decided not to stress it too much until I got some rounds through the gun and see how it runs.

    I can't recall the exact statement, but there was something about it being intentionally tighter to allow less gas to escape

    My friend had an issue with the enhanced bolt carrier and some brand new Rainier branded bolts. The bolts would not install into the carrier.

    His used Bushmaster bolt went right in and worked without any issues.
