If you want to search the internet for more feedback on their barrels, also try "BHW" or "Black Hole Weaponry". That is the name they previously operated under - and, usually, the name still found on their 'custom' barrels.
Rifling and bore quality is generally pretty good. -Which means they generally shoot quite well, too.
Fit and finish are pretty good.
Customer service is mixed. I've had good interactions to solve problems. But they've also burned me and refused to correct the problems.
But... I have gotten multiple short chambers from them, and have seen at least a dozen more reports from people claiming the same.
Lead time is on their website - or at least used to be.
I've usually gotten barrels on the early side of the window that they quote.
I currently have two of their barrels left here. Would I buy another? No.
I had to finish chamber and/or hone both of the barrels that I still own, after they refused to correct a short chamber.
They also "lost" my order once. I had to prove that they had charged me and provide a copy of the order receipt, before they even took me seriously. Then they "lost" the barrel from that same order. Then they delivered 12 weeks late (on a 6 week quoted delivery time). ...And the barrel had a short chamber.
Bottom line for me:
They're disorganized and unpredictable.
Twice, I've had to spend MY money to correct THEIR problems, because all they had to say about it was, "Yea, we screwed up. We're not going to do anything about it. Go away."
