Decent quality, dimple was off center

by -

Purchased this barrel for a budget build for a family member. Overall the barrel seems decently well made for the money. External finish was scuffed from the box, but no gouges or damage. Had no issues with accuracy. However, while I appreciate that they pre-dimpled the barrel for installing a gas block, the dimple was off center resulting in the rifle being undergassed when assembled. I had to run the rifle like a bolt action on range day. If they weren't going to do the dimple right, if have preferred they didn't do it at all. Submitted an RMA for a replacement.

Thank you for your feedback. We are glad we were able to get you taken care of with a return. Please do not hesitate to reach out if you have any questions.

Nicer than expected

After watching a video review on YouTube, it was clear this barrel was a very good deal. I was not disappointed. Even the finish on it is very nice. Nicer than any of my other barrels. This barrel for only 65$, you'd have to be insane not to grab one of these for your build.
