    that's what I was referring too with the POI shift.

    I think if I go the 'cut down' route, a 6920 or 6940 is a better choice.

    There is no reason to cut a Colt barrel.

    Agreed. Buy the Colt upper half/barrel in the length you want, and sell off the other upper.

    Not agreed. Milspec gas ports are huge if you're a suppressor user.

    If not, then they're fine.

    Well, then what would be optimal port size for running with and without can?

    With: .056'' (Will cycle full power 5.56mm unsuppressed.)
    Without: .071'' (Even if I prefer .062'')

    Both sizes are kind of subjective, and it's my opinion.

    Others are free to chime in.

    I disagree. I mean.... I run my can on a Bushmaster for Pete's sake. That is a big port. Just bump up the buffer to H2 or H3.

    If he cuts the barrel, the gas port is no longer spec for that length of barrel.

    You two are spinning your wheels. I am convinced this cat uses a pair of dice in his decision making process.

    Having the gas port sized smaller for a suppressor is a backwards approach.

    The gas port should be sized for mil spec ammo unsuppressed. That way it insures reliable functioning when the gun is dirty.
