Nerf Rival Knockout XX-100 Blaster 150 FPS. Condition is basically new. I just opened it and modded it. Upgraded to custom cut pro 25 spring. It’s been fitted with a brass barrel that is a direct line, air restrictor removed, and has had the seals perfected for a near perfect air seal. It’s really powerful, the dart is faster than the eye. It does great with worker gen 2 and gen 3 as well as dart zone short darts. I’m sure any Nerf darts that have been cut will be fine. It’s not picky even being brass. It’s going to make it out and quickly.
