The breech/receiver is not strong enough to support the weight of a rifle length barrel and shroud, a barrel band is necessary. The breech is milled from a hunk of billet aluminum, and when they cut that huge gash across it to accept the plastic Crosman style magazine it only leaves about an 1/8 to 3/16 of material on the bottom to deal with the mechanical advantage and torque of the barrel flopping around.
For repeatable high accuracy, a 30mm tube and the strongest scope mounts you can buy(and will fit) are requisite as they and the scope tube serve to reinforce the weakness of the breech, it's much like adding frame connectors to a uni-body car for the hot rodder crowd. This is not exactly an ideal situation. But, MANY airguns have this achilles heel, it's not limited to Hatsans by any means. Nobody likes to talk about it or warn you ahead of time.
That's kind of what I suspected.
