If there is a simpler bolt to disassemble that the Husqvarna 1900, I haven't seen it. Remove bolt from action, turn shroud clockwise with your hand 180 degrees and the bolt shroud/firing pin assembly slides out. To reassemble, insert firing pin/shroud assembly into bolt body and turn shroud 180 degrees clockwise and you're done. To tools what so ever needed.
I've only played with earlier Husqvarnas, but I'm not surprised that their last action was, too, very well designed and executed.
