Adjustable Blowstick Stock with Nickel Ferrule Use your original blowstick, but have greater control over the blowstick angle. This is the idea behind the swiveling blowstick stock. The ball joint adjusment gives lots of positioning options, and once you find the best angle for you, you can twist the knob to keep it there. At any angle, there remains good airflow through the stock. The Poly stock replaces your current blowstick stock, so it must be installed in your pipe bag. Compatibility: This part is pretty universal, but it may not be compatible with some products. Moose Valves will fit if the unit is taken apart and the valve installed in the lower portion. An additional water trap could not be added afterward, however. Gibson and Naill watertraps are also incompatible with this part, although others are fine.
