My Satern is a bad motherfucker, it's a 6.5 G, 20" and cut rifled. I got it years ago, I think it's a 1:8.75 twist IIRC. It's my most accurate rifle, most accurate barrel I've ever had or seen. Will do .33MOA all day with 120gr. BT's. But it's only good for about 1MOA, maybe a bit less with SMK's of various weights. I got the idea of the BT's from Bill Alexander, we used to talk from time to time when and just after I got out of the army.
But the button rifle barrels, if I'm not mistaken, are make by Liberty, which is/was a separate company, I don't know, maybe they bought 'em out and label 'em that. But as far as I know, only cut rifle barrels are marked Satern.
If it's cut rifle, get it. If it's button rifle, I don't know what to tell 'ya. Satern has 'em on sale on their site from time to time, just gotta check often. They're worth it. But custom ordering a barrel? Forget about it. My first one took three years, I never saw the second one.
But yeah, if it's cut rifle, get it. If not, wait and they'll have some for sale soon enough. Or you can go with another cut rifle mfg.
