    What is the gas port size of the tube being installed on the Noveske?

    It is the "suppressed carbine" size.

    Looks to be in the 0.05s.

    A great point here;

    A dedicated suppressed setup should NOT lock back without the suppressor.

    If it does, there is too much gas drive.

    After the rifle cooled down to the point that I could remove the suppressor, I did a lock back test on the rifle without the suppressor. The bolt failed to lock back but the spent case did fully eject.

    I will admit that I was a little skeptical about this gas tube but after Clint posted the picture of the tube that had about 4000 rounds through it, I was convinced enough to purchase one and give it a try.
    After trying it out today, Im satisfied that the BRT EZ Tune gas tube is a solid piece of equipment that optimizes the gas system of the rifle and allows the use of a much lighter buffer than normally could be used with a high pressure suppressor.

    Just received feedback on an LMT small frame application for a 10.5" CAR mixed suppressed using a SOCOM RC2.

    It works as expected with sizing the same as normal DI ARs.

    Because of where the regulation occurs, the barrel gas port has very little effect.

    This seems to hold with 45 degree gas ports too.

    My understanding is that Brownells uses the same gas port sizing as the SR-25 for their rifle length 20 barrel. I think I read that as 0.091? Is there benefit to limiting that at all?

    For those of us with LMT MWS platforms, he has some very promising gas tubes in the works. We tested one and it made my LMT run perfectly. When he makes these available, buy with confidence. I tested a 16 CL barrel. Made to run suppressed 100% of the time. It almost cycled without the can, and might without my XH buffer in the gun. It FTF on the 3rd round several times. With can on, it would lob the brass 3-4:00. Recoil impulse tamed nicely.

    Finally ordered one of the EZ-tune gas tubes for my overgassed 733 clone and took it out to the range today. Only fired 20 rounds of XM-193 and 86 rounds of Wolf Gold but my initial impressions are that the BRT tube has definitely mitigated the retard-level overgassing issue.
    I've got a couple more carbines I want to build in the future and might just get BRT gas tubes for these right off the bat instead of even bothering with the standard tubes.

    Clint,

    Like a previous poster, I am interested in using one of these to reduce gas drive on a rifle length system, in my case a 308.

    You mentioned that someone could order a midlength, and specify it to be changed to rifle lengths in the note. You said that it would be necessary to modify a standard tube. What did you mean by "modify"?

    Good deal.

    The tubes really do work.

    Not a bad plan!
