Disappointed in my first VQ product from United States, MN Public Profile

First off, the barrel shoots fine and is very light compared to the other barrels on the market with a similar diamter. The fit and finish is excellent. It does prefer the better ammo so be prepared for that. I had issues with the cantilever interfering with the top right side of an aftermarket takedown receiver. I was able to put the barrel on but could not take it off due to the interference. Another reviewer had the same issue. I contacted Volquartsen for assistance and never got a response. I have very little confidence in their customer service and warranty claims if they can't even find the time to help me make it work. I contacted the receiver company, another company based in Iowa like Volquartsen, and their gunsmith walked me through a fix. Ding one star for bad fitment, and another star for non-existing customer service.
