Turns your knockout into a hand cannon, you won’t be disappointed
This spring is incredible, I wouldn’t pair it with a short dart mod because it would shoot too fast and too hard, but this spring on a stock blaster shooting rival rounds is great!
Pain to install
after assembling the extremely hard spring my whole gun imploded because the spring got primed and it wouldn't shoot
This spring is very, very powerful. So powerful, in fact, that it sheared the plastic connecting the plunger to he plunger head when I accidentally dry fired it. However, my knockout was a TKO with the air restrictor removed, so your mileage may vary. The few shots I did get through it before it broke were amazing though.
