I have four primer catchers for the Rock Chucker IV/Supreme to give away. They will not fit other presses! As you can see, they are made from different left-over plastics - every one is a world-wide unique piece of art . They come with the collector tube and ram plugs. I will cover shipping. If interested, simply respond here with the number you would like to get, and pm me your shipping information. First come, first serve...
