Listed as one is nothing wrong with Nerf, it's tough!
You can "customize" this model with other parts (a gun was owned for example has added another N-Strike).
He pulls away and strong side darts, listed "missile" is more rustic: it is by direct action of the pump (it takes a bit of "nerve") shipped. Little precision on this side due to the pumping motion which moves the assembly. But regardless, the fun is waiting for you!
Listed security: very well thought out, the engine can not rotate when the inspection door is opened or if the charger is not engaged. As always it is best to use deprotections glasses (those of the brand are also very good).
Two (small) flaws:
Make sure to use darts in very good condition, otherwise it easily jams
Given the rate of fire, the charger 10 darts is clearly too small
In the end a very good product, as often with Nerf.
