One shotgun I always wanted just to have, and never bought, the Remington Wingmaster in 20 guage. I finally acquired one earlier this year. The shotgun was diassembled, new in the box at the store, just in from the factory. Foolishly, I did not assemble the shotgun and test the action at the store, I only looked in the box.
Once home, I removed the forearm with great difficulty. I broke everything down and cleaned the parts thoughly. Upon reassembly, things got pretty interesting. First, the bolt assembly was difficult to get into the receiver. The right action bar lever was extremely difficult to depress. The left lever was impossible. Not only that, but the action was rough as anything, not the famously smooth Wingmaster action. The action was jammed up tight at this point and would not move forward or backwards, but the bolt was stuck halfway forward of the ejection port. I had a few choice words to myself at this point.
BTW, this is not my first 870. I've been shooting them for over 40 years.
I called Remington Customer service the next day and explained the problem. My thought is that something inside the receiver was buggered up during manufacturing. The Remington rep provided me with the repair and service numbers and sent a UPS shipping label. I enclosed a letter with the relevent information and off the shotgun went.
Several weeks went by and Remington notified me that the repair process had started. I followed up with a call and was told that indeed the receiver had been miscut and Remington was sending a brand new shotgun to replace it. Sure enough, a week later, UPS showed up with a Remington box with a brand new Windmaster inside.
Remington stood behind their product and made it right in the best possible way. Great job Remington.
