none for the impulse i was always turned away by the banjo wire and how fragile it looked
new designs derlin bolt
does what its says
lowers volume in fireing chamber
this is a regulator for the selnoid of the impulse it is designed to regulate and it does it well. aside from what people think it is designed to increase the presure inside the the chamber that fires the paintball. this increases the shots per tank because it uses a smaller volume of air to project the paintball the same distance that a lower pressure would take. this also allows the impulse to fire faster because you can turn the dwell down. this product is best used in conjunction with the evil valve because they are designed to work together. this product is not as good a regulator as say the rock but as far as i can tell the ajustment does not change and its as consistant as it need to be. i have experenced no noticable shoot down even dureing long strings. people who experence this may want to increase the pressure going into the regulator. that should fix the problem. the one thing that i did notice was while shooting the gun rapidly the presure goes way down about 40 psi going into the selnoid. this i would think, would cause shootdown but it did not seam to effect the proformance of the gun at least in trials.
in conclusion this is an exelent upgrade in my humble opinion. i also advise buying the evil valve in conjunction to get optiomal effects of these outstanding products.
i give this product a 10 because of how effective it is and how the product effectively solves the problems of low shots per bottle count
