Things I liked: It's compact put together and even more compact stowed away. It has a full metal barrel and receiver and shoots well too. One of the coolest things is seeing smoke come out of this. It's pretty accurate, easy to break, and a decent weight. The scope isn't bad either. A good starter gun and doesn't feel childish.
Things I would have changed: Longer stock and iron sights. I'm not a fan of continuously putting on the scope to hit targets. The stock is made of plastic (doesn't feel cheap until you get to the butt stock) and the gun will be front heavy because of that. Lower the cheek plate if the stock is gonna be this short.
What others should know: Good plinker and (with the right ammo) can do some damage. You use an allen key (comes with) to loosen the receiver (barely). Then you insert the barrel and use the allen key to tighten it up. After that, you're ready to shoot. Therefore, nice simple rifle.
