18.6 inch cold hammer forge 223 wylde

Not hammer forged they don't.

Ordering a 20" FN hammer forged barrel and getting it cut down to 18.5" is the closest you're likely to find. 5.56mm chamber only though.

I don't think anyone makes exactly what you're looking for.
 
DD has an 18 inch mk12 profile barrel that could be nice if they would do a special 18.6 inch run for Canada.

I'd really like an 18.6"+ SPR profile barrel as well, be it chrome lined, nitrided, SS, I don't really care as long as it's "match grade" and can be expected to produce ~moa accuracy. >223, .223 Wylde, 5.56 or even .224 Valkyrie...
 
It's not known to many in Canada, but those Factory ACR 18.5" barrels are hammer forged and super accurate.

I've got the DMR(heavy) version and the Government (Skinny under handguard) that can launch 77gr OTM pills at 0.75 MOA regularly. Also tested between cold bore shot and while hot(After 150ish rounds), point of shift is nil for the DMR, and just maybe 0.5" for the government version.

The gas port is undersized(designed for piston), so you can either open it up to 0.078" (5/64 bit), or use a lightweight buffer/BCG system to run it reliably.

Eitherway, super accurate, durable, factory made. I wouldn't hesitate to grab another.

I actually did this with my 16" AR15 barrel, was one of the Questar takeoffs. Drilled it out to .078 and it's been 100% reliable and a nice decently accurate barrel.

I've been considering doing exactly what you stated with the DMR barrel when I eventually get an ATRS receiver set.
 
What do you want a CHF barrel for? As I understand it, CHF is of limited benefit outside of machine gun applications. I guess they are cooler than button rifled barrels, though.

International Barrels based in Chilliwack make a 19" CFH .223 Wylde. AFAIK this is the same barrel Ryan Steacey has used to win his last 4 of 6 Service Rifle Championships...

AFAIK, IBI barrels are button rifled, not CHF.

Even with a few 5-10 shot (pistol mag) mag dumps you can destroy the throat quite quickly getting the barrel hot. You don't even really need a 30 round mag to do so. Think of running a 3-gun setup and using Cross 10+10 doubled mags. You can get 20 rounds out very quickly. A couple instances of that can cause some pretty bad throat erosion.

Heck, a thread on ARFcom in the BCM (Bravo Company MFG) industry thread came to light that they said no more than an average of I think 17 rounds per minute or else you could void the warranty. Guy had a Drop in Auto Sear or something and shot the barrel out in a few hundred rounds.

The CHF MIL-11595e barrels resist throat erosion and damage far better than any other barrel types. So Daniel Defense, FN and even in this case the ACR barrels are actually really good barrels.

I learn alot from this! One I thought bcm was suppose to be top ter along with DD, guess not.

I knew CHF was better for "higher " shooting volume, but not to this extent!

I was under the impression that the dmr barrel was stainless and not CHF?

Here is the Wolverine add
