The “paintball markers” have been downplayed
Markers are designed for children ages 11+, smaller and lighter than classic paintball markers, paintballs are lighter and smaller in diameter (0.50″ cal. while standard balls 0.68″ caliber cal.), fire speed is smaller than standard paintball markers.
All together, it gives the same dose of adrenaline to a lesser-to-bone mass.
It’s fun for all ages, because kids can play together with their parents.
