I was doing a little research on having a left handed mauser built for me one time. If you're talking about rifles then their actions are very good and gunsmiths are happy to built a gun with them. That's all I concerned myself with back then. I don't think highly of their shotguns...but they do fill a niche of the market. (a $200 auto will always be a $200 auto). Sorry I don't know if there barrels are good or what the overall product is like. As far as functional or reliable....Well, in rifles you don't get much better than the mauser-styled actions IMHO.
