I recently bought and installed a noveske switchblock barrel and NSR rail on an M5 upper. Installation was uneventful. I finished up the handguard screws, and went to admire my handiwork, when I noticed that the gas block (switchblock, in this case) was canted. I took the handguard off and inspected the barrel, and determined the gas block pin was drilled at an incorrect angle, causing the issue.
I emailed noveske, and received the following response.
"This shouldn’t be an issue. We hand drill each barrel and gas block together, with acceptable + and – fit tolerance. Although your switchblock favors one side, you should not experience any reliability issues.
Please reach out if you have any further questions!"
Am I being unreasonable to think this response is a bit lackadaisical?20201006_214907.jpg Picture for reference, but it is more apparent in person.
