Type: BB Gun/Rifle. Manufacturer: Umarex USA. Model: Morph 3X. Materials: Plastic with some internal metal parts. Weight: 2.5 pounds (1134 grams). Barrel: 4.5 inches, metal non-rifled. Propulsion: 12 gram CO2 x 1. Action: Semi auto, double action only. Ammunition Type: 4.5mm BB's. Ammunition Capacity: 30 round internal magazine. FPS: 480+ I was pleasantly surprised with the Umarex Morph 3X CO2 BB Gun, I expected it to be much different from a lot of the other airguns I have reviewed since it is so versatile with all of its configurations. I was not expecting it to be so powerful with only the short 4.5 inch inner barrel. I was again surprised but the accuracy, not many BB guns get a 3/4 inch grouping at 30 feet out! Another kind of cool feature I didn't even know about at first is the ability to adjust the velocity using a screw for higher or lower fps. Lower fps will maximize the amount of shots you get from a 12 gram CO2 while higher fps is just kind of more fun to shoot in. I also don't often recommend BB guns for pest control but in this case with how light weight and easy the Umarex Morph 3X CO2 BB Gun is to break down and put in a backpack, and the fact that it is fairly powerful and accurate out to 300 feet. I feel in a pinch you could take down some small vermin if you found yourself hungry and lost in the woods.
