Arrived quickly and functions flawlessly

First, from over 20 years experience as both an FFL holder and a firearms enthusiast, I have always despised Century Arms going back from dealing with some hag named Gitta that considered herself to be a salesman to the fact that Century offers NO parts.......none, not even a screw for any item they sell.Their products or truthfully about 90% of their products are crap. The WASR 10 is a decent rifle after you throw the furniture made of Balsa wood into the wood stove and replace the crap with ANYTHING else. Century helped introduce the world to the Canik pistol and they are a great item for the money. The RH10 rifle is ok but its just a modified WASR10 with RPK sights with a rear sight slot too tiny to use without taking out your dremel tool to widen it. Their firearms are so "reliable" that Century honors their products with a LIMITED single year warranty....in short, it is one of the worst companies that operate in this country. These key wind drum magazines have functioned well for me however and I keep three of them fully loaded with the spring tension off ready to wind up and go to town when necessary. They actually work but do require cleaning and proper lubrication. Good drum magazine in my experience but I havent purchased one in several years. If they are the same as they were about a decade ago then yep, they are great drum mags
