Ko-Tonics 6.8mm barrels
I picked up an AR with a 6.8mm KoTonics barrel and from what I have found out is that this company had some serious chamber pressure problems from bad chrome lining.
Anyone follow this or know more about what happened? I see that they are no longer in business and am trying to get more info on the pressure problems people experienced with these barrels

I would get some pure led balls just slightly larger the a 6.8 bullet Push one starting at the chamber end and push out the muzzle The with GOOD quality dial indicator measure the ball bot land and groove diameter. If more then .002 smaller the bullet . than most likely when bore was chromed it got too thick and reduced bore diameter THUS high pressure. BE CAREFUL VERY VERY CAREFUL 0
