Helpful Positive Review High quality barrel, just as good as Proof or Christensen, I own all 3. by Hal, November 29, 2024
For the person who left a bad review and said it was over priced and to stick with Proof research or Christensen arms you don’t know what you’re talking about. This is a very high quality barrel that is a shooter. Also the barrel can be found on sal...

Helpful Positive Review Absolute Hammer by Steve, March 23, 2022
I was skeptical based on the price, but I have heard good things about Helix 6 so I decided to give it a try. I built it on a Daniel Defense rifle I had. Absolutely hammers. Easily sub-moa out of the magazine with factory Hornady 108s. Worth it. ...

Helpful Positive Review Comes with a gas tube by Ar, Verified Owner, April 19, 2023

Helpful Negative Review Buy a Proof instead… by Beast, Verified Owner, December 15, 2024
The people that are saying this barrel is better than a proof have exactly zero evidence proving their claims (Just like the company shills that made the video) that Helix barrels are better. I have at least a dozen Proof barrels and not one of them ...
