Does anyone have a parts breakdown/diagram of a contender the could e-mail me? (or a web site that has it) I cannot get my hammer block to drop after disassembling my contender and need a picture to see if I put it back together properly (obviously not). Please help as this is my sons new prairie dog gun and we are leaving for a hunt Thursday. Thanks in advance. Marc Heien Spencer Iowa. (mheien@mchsi.com)
