I would suggest re-torque all of the rail and receiver screws, especially if you've previously removed them. Or send it on RMA and we will gladly handle it and return it within days. All of The Fix rifles are shot for accuracy before shipped. 5 shot groups, not 3.
Accessories barrels are coming. Sorry for the delays.
I believe Proof now has barrel extensions and can build you a barrel. If so, they have drawings and can chamber them, as they chamber ours. We have never rejected a single Proof barrel for quality, including chamber. Their barrels are incredible. You can also use your current extension.
I never said I would release extensions for general consumption. And I'm not doing that. I said I will release them to a few selected barrels makers. Proof is the first, APA is likely the second.
I agree, you have more options with Remington clones. Not sure if they have a switch barrel or not.
And yes, things are taking off faster than expected. Extensions, and other key components are used for production rifles.
I appreciate your support and insight, but I will continue to make the decisions for Q that I feel are best for quality, customers, employees, and the future. On the bright side, with current demand, you can sell The Fix for more than you paid for it.
