Barrels are true mil spec to specifications per the militarys request and drawing.  Material, rifling form, chamber dimentions, chrome, finish, etc

This is the first govt procured barrel with a lo-profile gas block configuration instead of a FSB (NSN: 1005-01-633-2345), note that the journal for a FSB is still present if you wish to install one

One of the gas block dimples will be exposed if you install a FSB. 2 dimples for gas block set screws are present per the official drawing (spacing .425).  The markings on this barrel are also on the gas block journal in front of where the gas block is mounted

    AWESOME

    This is what I love about KAK. You get a product that is worthy of DoD contracts for the price of commercial products. This thing slaps. I built a MK18 clone with it and a Geissele Mk4 hand guard. At 25 yards it is shooting 3/8” groups with m193 ball. This is one of the softest shooting uppers I have. I’ve mounted 3 different suppressors to it (Griffin RECCE 5, YHM Res K, Gemtech Abyss 7.62) and none of them are gassy. This is what the MK18 barrel should have been.
