Was thinking about building another upper using KAK parts (barrel and upper receiver) but with a decent Midwest free-float hand guard. Do you guys think KAK is ok or should I look elsewhere. The upper I built I used Odin Works; nice but pricey.
I did a build recently at a SOTAR class with a KAK .300 Blackout "Mr. Blond" CHF 9" barrel. Cost me $180, and I had heard good things, so I thought it would be okay.
Issues noted:
1) Barrel had a burr at the muzzle and would not pass a barrel straightness gage. Chad had to re-crown the barrel to remove the burr.
2) Muzzle threads were not concentric to the bore. Used a Schuster concentricity gage to find that.
Things did work out. A suppressor gage rod showed that there wouldn't be a problem with my mount and can. (Some cans are looser than others, apparently.)
KAK did not reply to my email.
It's your nickel. My next build is getting a Criterion barrel.
Muzzle thread were not concentric to the bore???? Holy crap!!! How far were they out? Did you indicate them?
I thought someone on MDS had a build list that included a KAK barrel. I'll see if I can hunt it down. Maybe that was somewhere else and I am having a senior moment.
had my KAK 9x39 AR pistol out this weekend. I have to say I'm very impressed with the 9x39 rd and the accuracy of it ! had some short stroking at first unsuppressed. but after I suppressed it it ran flawlessly. I put a 3x fixed red dot on it. that wont stay long, as I can see this thing has more legs than I had given it credit for. now debating building a 2nd 1 lol.
Does it use AR mags?
