Ok, so I was actually very close...I was 2 days short of 9 weeks. I was messing with my boy Vu because clearly years was a typo, especially after 14 shots..lol. like he said, they havent around longer than a few years. Getting back to these powerful little pumps, I have run the mp10, jebao wp series and now the rw and imo the rw is the best jerry, the best.
