I can't understand some of these comments. I ordered, and received 2 complete trigger groups for a bullboss, 1 from Hatsan USA, and one from the over seas Hatsan site. Also recently ordered and received 2 valve pins for my Bully, and a complete valve assembly. Had a response and an invoice the next day after I filled out their form.
If I buy another Hatsan (springer/gas piston, no PCPs for me), which I am often tempted to do, I just plan on it being terrible and am pleasantly surprised if it is not.
I have ordered and received several parts from Hatsan USA, no problems, and FAST shipping. I don't know why some people have problems?
