Smart Parts Impulse - Undertow Bolt - Werm Stik Trigger - Dye Boomstick - System X 68/3k
The bolt is great. Lowered my operating pressure, Gives some extra range, not too much though. Gives some more accuracy at longer groupings. It's all good but ND puts out a great bolt also. It's also somewhat shorter than the regular stock impulse bolt so it's "faster".
Maybe it gives cancer? - Other than having to use two bore sizes bigger than the paint to get the extra range ad accuracy not much.
Great bolt, good price, most of the delrin bolts are the same but this one stands out from the crowd because of the extra range.
