    The majority are the same length, while some of the 5/8-24 are slightly longer.

    The 14.5" allows a wide variety of choices.

    We'll be starting production on the next batch first thing in January.

    Well that’s super tempting, I’ll definitely be paying attention to this thread more.

    ETA - Are you planning on going 1/7 like the 14" or 1/8 like the 16"?

    The plan going forward is for all versions to use the 1/7 match blanks.

    What rifling will they use? The 5R in my 1:8 Optimized is just a lights out shooter.

    The hybrid poly rifling.

    Should be even better.

    Must have missed this but is this mod0 chamber you reference modeled in any way after John Noveskes' mod0 chamber which AFAIK is designed for mk262 ammo specifically.


    NVMD, I see it's simply a standard NATO t.56 chamber and not a super tight match chamber.

    Has the first batch of the pre-ordered barrels shipped out yet ? Thanks
