Faxon did replace the barrel and the new one is better, but still not particularly accurate... By the way the barrel is very attractive and from all appearances is a quality piece, just not accurate.
I am not sure what that means. I am a bit of a barrel and scope nerd, and shooting begins with a reliable accurate barrel.
The most important part of the rifle, is the barrel. If it is not accurate, how is that good ?
I spend a fair amount of time with different barrels, and have worked with barrel smiths and blank makers and have come to know a thing or two about barrels. Not everything, and certainly still learning. The barrel begins with the steel and then the blank maker and ends with the shaper and chambering and reaming and, in the case of a gas gun, the gas port and timing of the extension. Barrel blank makers are getting better and better, but there are still a handful of names that I rely upon for barrels. And they are different names for 10.3" to 14.7" than they are 18" to 24," and different steels and so forth. The name you mention is not one that I am familiar with. I mean, I have heard of the name, but I have not used it or recommended it.
It all depends upon what you use the rifle for, and how important MOA or sub-MOA accuracy is, and conversely, how important durability is. They tend to be inversely related. There are plenty of barrels that will get you 1.5 - 2.0 MOA all day long, and even at 300 yards, that is enough to hit an enemy human target. In fact, the US military originally designed the M4 to be 1.5 MOA, if memory serves me, so not everything needs to have a perfect shot. If you are shooting to 800 yards or more, you will most likely want more accuracy than if you are shooting 50 to 300 yards. All of a sudden, 1 MOA starts to matter. So does velocity of the bullet, and so forth.
