FN uses M249 steel and chromes twice as thick without advertising it? Really? Never new that.

LOL! Neither am I, just found it interesting... but ya it's there to protect the crown. Then again, as is the chamfering which we more commonly find. I dont know what the exact advantages/disadvantages are between them. Centurion did at some point have something similar on one of their earlier HF barrels. Their Med Cons I think.

FN makes the M249.
Little over a year ago Rainier briefly had CHF barrels listed so I purchased one in 16" Middy with pinned gas block. I have bee very impressed with it....accurate and shoots well. They didn't have them long so I wonder if this Mountain series is an extension of that offering.
No, M4 barrels are button rifled with standard chrome lining. But afaik, FN does not make M4 barrels. Their M16 barrels I believe are button rifled and have standard chrome lining, as per the TDP.
I don't know for sure, but I read somewhere that they use 249 barrels for the SCAR, F2000, and P90.

PSA is offering a CHF M4 rifle kit with what they claim is FN "machine gun steel barrel with double chrome lining."

^That's different. Those barrels were manufactured by FN for PSA. Koshinn is referring to FN military m16s.
Nice. Now they just need some SBR lengths!
