Crosman 1077 Basic O-Ring Rebuild Reseal Kit - Contains 130-034 106-005 130-032 38-128 Stop! Important! Read! This kit is designed to repair current generation 1077 models. These parts very well may work fine on earlier variants, but nothing is guaranteed. Purchase at your own risk and NO returns if the parts don't fit. Kit includes: 130-034, 106-005, 38-128 & 130-032 x2 Instructions are NOT included and the you will need to completely disassemble your 1077 to install these parts. I suggest watching online tutorials or other guides on how to perform this rebuild, if you so choose.
