Crosman DPMS SBR. Need trigger help

Well, my daughter bought me one of these. The trigger was so bad, I called Crosman and sent it back. The replacement trigger is just as bad. It has a trigger pull that must be 20lbs. Before I sent this one back, anyone have any suggestions on how to lighten or smooth up the trigger? I am not expecting 1911 match trigger but something I don'thave to use 2 fingers to pull it. Thanks in advance
