The wheels are incredible,when combined w diamond/chili darts and a Daybreak cage it’s a force to be reckoned with,these were my 1st time replacing flywheels in a stock blaster and I 110% don’t regret it,if you’re modding a MK 3 or other blasters,these are amazing and recommend it to the highest degree,high quality work,absolutely plan on probably using em in future mod projects
