I recently picked up one of these little guys. I have not had a chance to modify it at all, but my initial impression is that this is a great little gun. I have had it out a few times with zero issues, it shoots straight and actually has a pretty nice trigger. The only thing that I see that may be an issue is the plastic sights, but for now I think they'll be fine. It's fun to shoot and fits in a back pack easily, so it has a good place in a BOB. I'll post some pictures if I end up modifying it, but until then I'll just enjoy shooting it!
