The First autococker is an '04 I believe and it does have a leak in the LPR but I'm positive it just needs adjusting-will not matter if you convert it into a pump. The red/black is an '08 I believe and it has no leaks. I was going to turn these into pumps but changed my mind. They come with a brand new pump kit and this autococker threaded barrel I was given with the guns.
