Hasbro's Nerf Assembler Gear Avengers Infinity War Star-Lord Blaster is recommended for ages 5+. It includes three elite darts. The blaster has three pieces and it's completely modular. There are 4 other Avengers blasters, each sold separately. You can mix and match all blasters together. Insert a dart into the front of the barrel and pump to load a dart. Pull the trigger and off the dart flies. The dart flies, but not terribly far, and with one dart at a time, it pales in comparison to the performance of most other Nerf Blasters. Of the 5 Infinity War blasters, the Star-Lord is the least inspired. So, although I love the Star-Lord character, I have to say that this is not my favorite blaster in the galaxy.
