I don't have a Kraken, but I do have 4 others from Cadex. I'd consider buying the Kraken, but the barrel swap and factory interchangeable barrels needing to be produced for your serialized rifle holds me back some. The words I used are exactly "There is no differences from AI shipped barrels", there is none as far as the consumer/buyer is concerned. You can not order but a single part numbered barrel from AI for that caliber and length. I seriously doubt AI is delivering barrels out of spec. Could it happen sure anything is possible, though very unlikely.
I have more then a dozen of both small and large shank AI barrels, none of which showed any of the problems as described here. I'm not coming from a sample of 1 mind you. The requests for you to provide part numbers was to refute your "100% false" comment.
The problem you mentioned could be more related to 3rd party smiths making prefits that could be subjected to more tolerance stacking.
If AI in your opinion can get it right for the AXSA small shank, why then would they potentially fail with the AXMC large shank?
I'm more then willing to accept AXMC/AXSR owners here on the hide saying factory AI barrels failed to headspace correctly on their rifles. That's no different then my claim that mine all work, and frankly I'd raise hell with AINA if they didn't.
AINA subs out the barrels, they are Bartleins and chambered by WinTac currently. Either could have a bad apple, but I never hear of people returning AI barrels due to them being defective.
Keep up the good work calling people 'Gentleman'
