Carefull with the Phantom. You may find you get better accuracy from the iron sights. The barrel lock up area uses plastic washers and there can be quite a bit of sideways play of the barrel rendering the scope "cute" but less accurate than the barrel mounted iron sights.
What I did with my Quest (wood stocked version of the Phantom) is change out the washers for metal ones can you can find at your local hardware store. There is far less barrel play and the scope does do better.
Also, make sure the scope bases are tight and up against the scope base plate on the rifle or else the scope will move along the dovetail ramp.
