I just purchased the tristar viper g2 camo. I really like how well the stock an everything fit together. Guns of much higher price are no better. As soon as I got home with It I disassembled it and cleaned it. Then lubed it up with a light coating of Rem oil. Took it out and ran a box of mixed ammo through it. The first 5 or so shots were with heavy load of super x. They worked perfectly. I then mixed light and heavy loads in it and shot it as fast as I could pull trigger. It cycled them al through perfectly. I am convinced that you can spend hundreds of dollars more and still not get a gun of better quality. All manufacturers have a lemon occasionally get through. Although I think maybe most of the complaints are coming from people who don't know what they are doing or are name snobs. These are great guns and I firmly believe it will last for many years.
