Chrome lining question

[ODgreenpizza]

FN produces their own chf ar barrels in house.
Check out the description of the chf FN barrels on the FN site and compare it to the descriptions of chf barrels from Centurion, Noveske, Rainier Mountain Series, PSA, Spike's.
It's possible the upper in the OP was assembled by FN as they have an identical upper on their site.
FN also has non chf barrels available, idk if they produce those themselves

Machine gun steel and double thick chrome lining are pretty universal in descriptions for CHF FN barrels. It may be hype, but its not PSA's hype.

The other problem with PSA barrels by FN is/was that the carbine barrels came with PSA spec'd gas ports. I remember the 10.5s, I think, at one point coming with the huge ports. Rifle, however, should be standard port size.

Thats a 16" - the 20" barrels are always out of stock: https://palmettostatearmory.com/psa-...mp-barrel.html

My mistake. I had made the assumption that we were talking about 16s.

We may well be, but the OP referenced a 20 incher.

I have had fairly bad results from the "double thick" chrome lined barrels. I have a Noveske 14.5" that averages at about 3 MOA. I have a 18" FN that shot 1.9 MOA on my first group, and not less than 5 MOA on all subsequent groups, regardless of ammo. It sits on my shelf.
