Nope. CA provided their specs to FN, and FN makes the barrels. Just like all these other companies selling FN barrels. In fact, someone on arfcom posted a link to FN's website where they clearly show a CA marked barrel as an example of their work.

Personally, I don't see the PSA or Spikes barrel shooting "better" than the Noveske or Centurion barrels. If anything they will all shoot about the same.
I believe when the smoke clears it will be obvious that all these barrels are much more alike then they are different.
These barrels are all made by the same company on the same machines from the same blanks, have the same chamber, chrome lining, rifling twist and barrel extension specs. It also appears that the profiles are identical on some of the models. All these barrels also appear to be HPT and MPI.
The only real unknowns are are the gas port sizes, how the crown was finished and whether or not all of these barrels actually have a tapered bore. However I would expect the differences to be negligible at best.
If you build your own guns and know what you are doing I don't think you can go wrong with any of the FN manufactured CHF barrels.
If you want someone to build a gun or an upper for you then I recommend that you spend the extra money to get the attention to detail that is expected from Noveske or Centurion Arms.
Here's my FN CHF Barrel Chart.;)

* I did not include BCM because it has not been confirmed that their BHF barrels are made by FN.
**Gas port size for Centurion and PSA based on Comp1911's pics and descriptions on page 7 of thread on TOS - PSA was tight fit with 5/64 drill bit and Centurion slightly looser with 5/64 drill bit.
Stickman,
No one here is playing wet nurse. I think many of us have been wondering about these barrels for some time and genuinely just want know how, exactly, they are different.
I don't see this as bad thing. Once the details are known about these barrels everyone can decide for themselves whether or not the differences are worth the extra cost and make their purchase according to their needs and wants.
Edited because I can't type for crap on my smart phone...:p
