Group Buy barrels any good?

[lazyengineer]

Difficult to be sure, but at some places it seems like the lands go all the way to the beginning of the breach, and some maybe not as fully.
[Edit - I looked anew with a better bore-scope, and the throat does look more uniform than some of these earlier photos suggest]

Overall, for a sub $200 BBL, this doesn't really look bad. I wouldn't call this super premium (tool chatter, eroding maloniting), and I'm not so sure the lands in the throat are all starting perfectly. I don't think it's impossible for this barrel to shoot near 1 MOA, though I will say, right now for me, I only get there with 90 gr TNTs.
