SixFive vs Shaw barrel

[aknott1994]

Thank you, I'm not having any issues other than some sooty cases most likely due to the mid length gas system, which i could probably fix with an H2 buffer or adjustable gas block. The barrel is an 18" and I am unsure of who makes them, you can buy the complete rifle for $600. I am mainly looking to pick up a little velocity to reach out a little farther. No real complaints on the current barrel, it has a tight chamber and shoots sub MOA factory ELDMs.
