So far has this been pretty reliable? I got a 15 inch barrel I'm waiting on to finishAdd a pin to the inlet hole to remove head space. A little bit of volume goes a long way along with a larger transfer port and matching barrel transfer hole. 16 pumps with a pump cup with the previously stated mods and 15.49 pellets. Flat top will do much better and with less pumps. View attachment 498271View attachment 498270
