Satern barrels are great --IF you can get 'em. I had one on order for 2-3 years, had moved in that time and almost given up when they called and said it was ready to ship. They can do rifling down to the thousandth of an inch, hardly anybody else does that. Anyway, my heavy 20" barrel is by far the best one I have, it's capable of .33MOA consistently with the right ammo, and ~1MOA or less with most anything else. It's amazing. As for the chamber, well, it's got the chamber Bill A. told 'em to cut way back when. The chamber could be a bit longer IMO, but when you have one doing .33MOA, you don't fuck with it.
I had a second barrel on order with them, a custom 14.5 double deep, double fluted, gave 'em the drawings, and everytime I called I got an excuse and was told it'd be made in a month, or next run, or this or that. After 3-4 years I gave up, but never cancelled the order. Still waiting on that call. Been, oh, 5 years at least. With Satern, if they don't have the barrel you want IN STOCK, don't bother. The fact they can do this or that is irrelevant because they don't really do custom work, they do bulk work. So sometimes they have some left over. If you see one that fits your bill, get it. Chances are you won't find a better barrel. They're expensive for a reason. But Krieger would be another place to look and there are other cut rifle mfg.'s out there.
I have a Lilja SBR barrel I haven't used yet. 11.5" Grendel. When I get the toolhead and conversion for the 650 I'll load ammo for it and take it out. Until then it just sits. But properly rifle barrels using buttons do just fine IF the buttons are high quality and changed out before wear and tear affect the rifling. Lilja is known as one of the best, if not THE best, in button rifled barrels.
Liberty is another barrel brand Satern sells. I understand it was another shop entirely, maybe another business early on. I don't know if by now they've aligned themselves with them or if they're invested or if they bought 'em out. But Liberty button rifled barrels aren't made by Satern or in his shop.
