Keep the FX2000.
The Hatsan Factor is toward the value end of the market. It is heavy, it is long once a moderator has been fitted. The shrouded barrel works but not enough.
The massive 21 shot magazines work but the spring on the rotor is so strong when full the pellets can deform.
Mine wasn't accurate until it was recrowned.
If your thinking of your lad look after the Kral np03, lower shot count but handling for a junior.
Also consider the SMK PR900. More of a standard looking rifle, lightweight, also available in a black tactical stock but not adjustable.
Either the regulated version or the standard one. Those who know rate the standard better.
Repariere nicht, was nicht kaputtist.
