    barrel life ? after moving gas port.

    hi.

    i've sent my 16''CMMG mid-contour barrel to ADCO,

    trim her down, get some weight off.

    also move carbine gas, to mid-length gas,

    so ? we'er plugging one hole n' drilling another.

    other board guys are saying , that once you drill through the chrome, it'll pitt and flake, and barrel wont last.???

    what you guys thoughts on this ?

    No difference the original gas port was drilled through the chrome lining it doesn't cause problems. The other one will be no different expect it will have less gas port erosion than the carbine gas port because it will be tapping the gas farther from the chamber = less pressure.

    accuracy will most likely not be effected. no, it will not "flake." the chrome is chemically bonded to the metal, not plated on like bumper chrome.

    fear not.

    How much will the work cost you? It may cause the chrome to flake but if it doesn't have an adverse effect on performance it's pointless to worry. Then again, it may not flake at all.

    It will allow you to try a new barrel profile & gas tube length without having to pay full price for a new barrel.

    When was the original gas hole drilled? Before or after being chromed? If it was drilled after then it's too late to worry about flaking

    before or after ? now that i'ed have no clue.
    but if it was chemicaly applied, then no worries, ?

    i would think ? just guessing, drilled after ?

    it was drilled after the lining, and again- it will not flake... it's not a "plating," it's a bonded lining. misty is incorrect.
