    Some people like Noveske have done hard work to figure the best gas port sizes for they're barrels why should they just give away their data? Also sometimes if you really tune a barrel to work one way or the other that particular barrel may have it's own port size that works best. The next barrel from that same batch will require a different port size to do the same thing. Sometimes it's just a gas port 'range'. So publishing sizes doesn't accomplish anything.

    For that configuration, the "correct" gas port diameter is 0.062" if I recall correctly. My limited exposure to gas port dimensions and SME's who talk about such things leads me to believe that Colt/BCM/LMT/DD et. al. hover right around 0.062", whereas the shit tier makers sometimes have bigger ports to overcome rough actions and mild .223 ammo.

    Now, if you're shopping for an SBR upper, or a midlength, then you're already outside the scope of The Chart. I'd recommend looking for other sources of information, rather than bugging Rob for perceived shortcomings in The Chart.

    On the other hand, I think it's pretty dumb to play like gas port diameters are classified info, or a dimension that's not worth knowing. The original purpose of The Chart was more or less to track compliance to the TDP, and I bet you somewhere in that legendary document is a spec for gas port diameter.

    I disagree. Basically, I think all the seasoned experts, veteran know-it-alls should lighten up and remember what its like to be a noob. We all start out at the same place!

    We do, and we're trying, but some of you are too busy looking for reasons to get offended to listen.

    I wish someone would have smacked me in the back of the head when I asked silly questions that even if I had the answer to I wouldn't have known what do to with the information.

    As a noob to SBR I have found this forum helpful. I used the search function to track the development of expert opinions over the years and found gas port size was a topic for discussion 2-3 years ago. This does not seem to be the case in the last year as the operational aspects of the "recommended" carbines in the 10.3 to 11.5 range seem to be pretty well sorted out.

    The bottom line for me is I plan to buy two of the "recommended" brands (hope to have it in time for EAG at the end of the year) and if one takes a shit in class I will have another. To that end my main concern is end user support. Next I will search who is "recommended" in this regard.

    In my case, I was comparing the DD MK18 upper to the Noveske MK18 upper. I wanted to buy the unit with the smaller gas port. Couldn't find that information anyway, so I went with the Noveske because it was cheaper.

    amac,

    You're missing the point. If I told you that Noveske used a port size of .074 which buffer would you use? How would you make that selection?

    The correct question would have been this. I am going to purchase xxxx Noveske upper and I would like to know which buffer seems to work best with that size? However, I would have called or emailed them first or asked Todd.K.

    In addition you mentioned ammo and barrel break in. Barrel break in has been discussed a hundred times and Noveske has a break-in procedure mentioned on their website. Asking whether or not using steel case ammo in a Noveske stainless barrel would also have been legit. In which case some will tell you not to do it.

    I here you. With each new weapon, I learn more and more about functionality - what works and with what, etc... As mentioned, this is my first SBR. I feel like a kid waiting on Christmas - and it's January! The rifle is stuck at Lawmens. The tax stamp is waiting on Gomer at the ATF. You know the drill. I just want to shoot the damn thing!

    Waiting sucks. So, I diagnose based on others' posts. I almost ordered an A5 buffer system b/c others did so for their SBR's. It's a disease I tell you - running rampant throughout these forums.

    As for gas port size, while seemingly inconsequential, I wanted to know for personal, technical reasons. I do plan to suppress and feel this info may come be useful. I already knew I needed an H2 buffer - based on what I've read on M4C.

    Anyone with a pin gage and cash to buy a Noveske barrel can measure one. If Noveske is that uptight about losing their "secret" information, they're in the wrong business.
    Oh no, not another lube thread! Read this first: Lubrication 101.

    There's a big difference between giving out your info and having it reverse-engineered.

    +1, I deal with this type of stuff on a daily basis...
    Professionalism, it goes a long way.
