The K-force dart blasters are popping up on store shelves now. I found them at my local Walmart (where the prices are considerably better than K’nex’s Online store). Having both an interest in K’nex and dart guns, I picked up the cheapest kit on the shelf to tinker with. For what it is, the parts that make it a dart blaster are surprisingly solid, and it works with Nerf darts. You can probably buy a good nerf gun with more shots for a better price , but the K’force can be rebuilt to suit a number of cosmetic and practical functions.
