Roll pin hole was off ≈10° (pistol length) - Ballistic Advantage Gas Tube QPQ Coated

Quality of the material and meloniting were good, but the hole for the roll pin was off ≈10°. It made installation a SOB and took three roll pins to beat it into submission. Because the hole wasn't drilled absolutely perpendicular to the dogleg in the tube, it ended up looking wonky after I got it put together and caused issues with the carrier not wanting to go fully into battery. I'm buying one more to see if the first time was a fluke or if I need to look elsewhere for gas tubes. Kinda crazy if a barrel manufacturer can't get their gas tubes right, but we'll just have to see. I will update this review with my findings as soon as I get the new one.
