This a bottom-of-the-line thing, fires plastic BBs, 6mm, I think, and it's not a tack-driver. It will hit a big target up close, and that's all I want. Six rounds, plastic shells for the BBs, and it only shoots single action, using a spring and air, and while it will put your eye out or sting you pretty good if it hits you, the little balls are not designed to do any real damage to anything past paper. If it lasts a couple months and then goes kaput, I'm not out much.
What was amusing were the safety instructions, in Chinese and English. They are pretty good, insofar as what they tell you about not pointing the thing in the wrong direction and all, but the images are hilarious, and a couple of the translations amusing, too. Click on the image and enjoy ...
