Last Chance Block Kit Black. Install these blocks onto any LCA press that is copper in color. By upgrading you'd remove the narrow 2.5" blocks and install wider 3" blocks to help accommodate wider limb compound bow models hitting the market. Interchange the blocks easily following a few simple steps. See the instructional video below 2024 Mathews bows will require these wider blocks but the additional width can also help with other models like Prime Elite Bear Hoyt PSE and more. If you have any LCA green or Pack-N-GO bow press models purchase the 3" Pin Kit instead of the 3? Block Kit.
