The two biggest concerns are the click from priming (can be reduced in some blasters by holding the trigger while pulling back the primer) and the noise from firing. That's a bit harder to control.

To do this, you'd have to basically stuff the whole thing with some sort of fiber material or dense foam. You would also have to put pads between any two moving parts that make contact with each other (the plunger, the catch, the primer, etc.) and you'd still have the sound of air coming out of the barrel to deal with, which there is no easy way of dealing with for a dart blaster. Lubricants could help with sliding parts, but would also have a small but noticeable impact on performance.
