I usually don't chime in, so I want to apologize in advance. When you are dealing with companies that mass produce a product, through machining, etc, there is always a chance of production issues. These companies pump out thousands of units in a day, and sometimes are not aware of the production issue until there is a mass return on that particular product.
I have several rifles, as we all do, and can tell you that I have had minor - major problems with just about every brand. Thirty years ago, PRE-LAWSUIT era, I had a brand new rifle that had less than 100 rounds of factory ammo put down the throat. I started noticing problems with accuracy and ejected cases. Turns out that a hairline crack formed in the chamber, that eventually would have caused a serious health issue. I was 12 at the time and my dad called the company, inquiring about the 30 calibre handgrenade he just bought for his son. The company made good on it, but what a catastrophe.
Different brand rifle, 15 years later, ejection problems/accuracy issue (minute of buckshot at 100 yards). By the way, this was a factory rifle I bought off the shelf that was nearly a grand back then (1moa guarantee off the shelf). After taking it to the gunshop, turned out that the ejector was bad, and the throat had severe imperfections. Factory made good on it, but it was a process.
I feel for anyone that spends their hard earned money to purchase problems. Don't get me wrong, I do not agree with it, nor am I defending it, but I expect it at some point.
Just my two cents, for what its worth........
