Shilen barrels from midway

[Fess]

My only experience with Shilen was not good, although it was with a barrel blank, not an AR barrel. It was with an experiment with a bull-barrel conversion of a 7.62x39 Saiga (yeah, it is a silly project, I know). The barrel strung badly as it heated up. It is, of course, possible that the gunsmith screwed up when turning it down, but the next barrel, he says, worked great. Now if I could only get the danged thing back from him!
