I guess your right. I've read many different opinions on this subject. Many say that Walmart carries a lower end product because of there buying power to sell at a lower price then all competitors.
Since the gun was on Winchesters site and there's literature on it, I'm feeling better about what I have. I've read many strong reviews about the DBM, except for one problem. The spring in the Magazine apparently breaks. But, since it's 20 years old and still kicking, I shouldn't have to much to worry about.
Now, since the gun was only made for ONE year, I need to get in line and find a couple back up magazines, just in case. Apparently they're extremely hard to find.
