Part 2 of making my 4000 PSI BIG GAME PCP. In this video I built the hammer system, I estimate there will be 1 or 2 more parts, depending on how much footage I get. This functions great at 3500 PSI, although it would withstand 4000 PSI. At 3500 PSI the hammer functions better. In the next part I will be making the chamber, transfer port... etc
