IMHO, both are excellent choices.. but while CHF and CL'ing has come a long way, there isn't a way to "guarantee" 1 moa from those choices....To many variables involved.

And you might get lucky with a CHF CL barrel... I have had very good results from PSA uppers with FN barrels.

I would be more comfortable skipping the CHF requirement, and buying a Criterion CL... especially if you are looking for 1 moa "guarantee" .

Or, I would buy either the FN or DD , and try to see which ammo the barrel prefers.

And , first time I had heard FN tapers some bores.. very interesting.

I'm not so sure that an  "FN barrel" is an "FN barrel".

I would think that machining/specs are to customer spec more than some think.

Of course, I have zero data showing this. Curious of anybody has any real info....

Quality is not in question. Obviously at least some are calling out additional specs.

Interesting article HERE.

Monty mentions how FN CHF bbls have a "tapered bore in the last portion".

So, do ALL FN CHF bbls have this taper? Hodge and Centurion use it, is it customer spec or across the board?

Found this response by Monty. If I am reading it correctly, bore taper is inherent to the CHF process.

"I was given a link so I figured I’d come over and respond. 
Looks like you guys pretty much have the concept. The bore gets slightly smaller as it moves to the muzzle end of the barrel. 
I did not come up with the concept and it is not new. So why have you not seen taper bores in the AR platform before?? Probably because using hammer forged barrels is a fairly new thing in the AR rifles. Taper bore is something that is only realistically done by the hammer forging process. The mandrel that is used to put the rifling in the barrel is slightly tapered and this leave the tapered dimension in the barrels as the forging machine beats the blank around the mandrel. 
So what does it offer you? Taper bore gives you a slight boost in velocity over a non-taper bore barrel and it help negate any potential accuracy issues caused by chroming the bore since it is not always a consistent thickness. 
Taper bore does not extend the life of the barrel our barrels last longer because they are hammer forged and made from a different spec material that was engineered for machine guns. Hammer forging work hardens the material and the chrome is thicker than a normal barrel. The barrel steel is the same used on the MAG58, 240, M249, MK46, and MK48 machine guns it is also the same barrel material and process used on the 1/2moa sniper rifles FN won the FBI contract with and that are still in service. The FN SPR sniper rifles use hammer forged hard chrome lined taper bore barrels to get ½ moa accuracy and this is the same barrel specs and processes I have done to my barrels. 
So who else uses this? 
Obviously FN, who has the time, money, and resources to do the research to find this type of barrel steel and proof out this type of process and specs. FN hands down manufactures the best machine guns in the world and there isn’t even a close second in this field there isn’t even any two companies you can combine that has as much institutional knowledge as they do in making beltfed machine guns. 
HK also taper bores their hammer forged barrels for all their rifles. 
So why do I use it? 
Well I didn’t really think much about hammer forging and taper bore before I was sent to work doing combat systems development and operational testing for SOCOM. There I worked on several weapons programs one that used these barrels on one of the rifles we were testing. I got to observes millions of dollars worth of R&D and testing that was done and got to see hundreds of thousands of rounds run through these weapons and got to see firsthand that these barrels did indeed last allot longer and on a whole shoot better than standard button rifled barrels that were chrome lined. The difference was significant and I wondered why the hell no one made these barrels for the M4/AR rifles so I figured I would bring them to market myself. I have over 20 years of service and have shot out plenty of M4’s in my time and can with full confidence say this is a improvement I’ve seen it first hand. 

Thanks

Interesting info. I had zero idea.

Guess it's time to add an FN CHF to my kit.

Indeed.

" FN AR­15 barrels are hammer forged using the same proprietary high­grade Chrome Moly Venadium steel used in FN’s venerable machinegun barrels produced to handle the punishment of sustained fully­ automatic fire."

"A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as “Machine Gun Steel” by virtue of its required use in FN’s M249 and M240 weapons."

It's in the steel blend.

Yeah, CHF and button broached offerings.

I've learned a bit on CHF bbls this week as well.

Criterion will get it done.

FN makes barrels for other folks as well, such as Spikes.

Last statement that I read from JH was that his bbls are "9310H Modified steel".  Is this still the case?
Essentially a modification blend of FN's recipe.
